Feeding Your Family Well: Nutrition From Infancy Onward

Almost every piece of nutrition advice written for parents assumes the problem is information. It usually is not. Most parents already know that vegetables are good and soda is not.

The problem is that feeding a family happens at 6pm, with someone crying, after a full day. So this page is organised around the decisions that actually get made, in the order children grow, and it starts with the one rule that carries more weight than all the rest.

The division that makes mealtimes survivable

You decide what is offered, when, and where. Your child decides whether to eat it and how much.

That single split resolves most feeding conflict, and holding to both halves is what makes it work. Stocking the house and putting food on the table is genuinely your job. Eating it is genuinely not something you can make happen, and the attempt is what turns dinner into a battle that the child wins every time.

Practically, that means no bargaining, no dessert used as payment for broccoli, no separate short-order meal cooked on request, and no comment when a child eats nothing. Offer the food again another day. A child’s appetite varies enormously day to day and evens out across a week — and pressure at the table is one of the few things reliably shown to make a child eat less of a food long-term, not more.

Picky eating in toddlers and preschoolers is normal development, not a problem you caused. It typically takes many neutral exposures to a new food before a child accepts it, and “neutral” is the operative word.

By age

Birth to six months

Breast milk or formula, and nothing else — no water, no juice, no cereal in the bottle. A young infant’s kidneys cannot handle extra water, and it is genuinely dangerous rather than merely unnecessary. Feed on cue rather than on a clock. Vitamin D supplementation is recommended for breastfed infants; ask us for the dose.

Six to twelve months — the window that matters most

Solids start around six months, when a baby can sit with support, holds their head steady, and shows interest in food. What you offer in this window matters more than at any later age.

Start with iron. Iron stores from birth run down around six months, and iron deficiency in infancy is the most common nutritional deficiency there is — one with consequences for development, not just for blood counts. Iron-fortified cereal, pureed meat, beans, and lentils all do the job. Pair them with fruit or vegetables, because vitamin C improves iron absorption.

Introduce common allergens early, not late. This is the guidance that reversed, and it is the most important thing on this page. Parents were once told to delay peanut, egg, and other allergenic foods. The evidence now runs the other way: introducing them in age-appropriate form starting around six months, and keeping them in the diet regularly, reduces the risk of developing a food allergy. If your baby has severe eczema or a known egg allergy, talk to us first — that group needs a plan rather than a general rule. Everyone else should get peanut and egg in early, in a safe texture.

Not before one year: honey, because of infant botulism risk. Cow’s milk as a main drink, because it displaces iron and is hard on an infant gut — small amounts in cooking or yoghurt and cheese are fine. Added sugar and added salt, neither of which an infant needs at all. And juice, which the AAP recommends avoiding entirely under twelve months.

Choking, which frightens parents more than anything else here. Avoid whole nuts, popcorn, whole grapes, raw hard vegetable sticks, chunks of meat or cheese, hot dog rounds, hard candy, and spoonfuls of thick nut butter. Grapes and cherry tomatoes get quartered, not halved. Nut butter goes on thinly, or thinned into other food. Sit the baby upright to eat, every time, and stay with them.

One to three years

Whole milk from one year, and here is where parents get caught: it is easy to give a toddler too much. Roughly two to three cups a day is plenty. Beyond that, milk fills a small stomach, displaces iron-rich food, and is a common cause of iron deficiency in otherwise well-fed toddlers.

Growth slows sharply after the first year, and appetite slows with it. A toddler eating noticeably less than they did at eleven months is usually a toddler growing at a normal toddler rate, not a toddler in trouble.

Expect a stretch of eating only beige food. Keep offering the rest without commentary. Small portions, self-feeding, and family meals where the child sees adults eating the same food do more than any single strategy.

Four to twelve years

The school years are when habits set, and the levers are environmental rather than conversational.

What is in the house gets eaten. What is at eye level gets eaten first. A bowl of cut fruit visible on the counter outperforms any number of conversations about fruit. Eating together, when the week allows it, predicts better diet quality and better outcomes across a surprisingly wide range of measures — and it is one of the few nutrition interventions that also happens to be pleasant.

Two specific things worth defending: breakfast, because children who skip it concentrate worse at school regardless of what else they eat; and water as the default drink, which is the highest-leverage single change most families can make.

Teenagers

Adolescence has the highest calcium and iron requirements of any stage of life, and the least parental control over intake — which is an awkward combination.

Calcium and vitamin D matter now because peak bone mass is largely built in these years and cannot be recovered later. Iron matters particularly for menstruating teens and for athletes; fatigue in a teenage girl is worth a blood test rather than an assumption about screens and late nights.

Caffeine and energy drinks are the live issue. Energy drinks are not sports drinks, they are not regulated as though children drink them, and they carry caffeine doses that cause palpitations, anxiety, poor sleep, and occasionally worse in young people. The AAP position is that they have no place in a child or adolescent’s diet. Coffee in moderation in an older teenager is a different conversation.

Protein powders and supplements are heavily marketed to teenage athletes and almost never necessary — a teenager eating normally gets ample protein from food. Supplements are unregulated, contamination is documented, and the money is better spent on groceries.

If a teenager’s eating changes in ways that feel driven rather than casual — skipped meals, rigid rules, food logging, cutting whole categories, exercising to compensate, secrecy — please call us. Eating disorders are far more treatable early, they occur in boys as well as girls, and they occur at every body size.

The single-nutrient questions, answered honestly

The old version of this blog had separate posts on dietary fat, sodium, sweeteners, and nutrition labels. Here is what each of them actually comes down to.

Fat. Children need it, and the low-fat instinct that adults apply to themselves is actively wrong for young children — fat is required for brain development, which is why whole milk is recommended under two. What matters is the type: oils, nuts, seeds, avocado, and fish, rather than fried and heavily processed food. Do not put a child on a low-fat diet without a provider involved.

Sodium. Most of a child’s salt intake does not come from the shaker. It comes from packaged snacks, deli meat, bread, canned soup, pizza, and restaurant meals — which means reaching for the salt less at the table changes almost nothing, while cooking at home two more nights a week changes a lot. Excess sodium in childhood raises blood pressure in childhood, which is not a distant adult problem.

Non-nutritive sweeteners. The honest answer is that they are not the main event. For a child, the significant thing is the habit of sweet drinks, not which sweetener the drink uses. Swapping soda for diet soda keeps the habit intact; swapping it for water retires it. There is no established harm at typical intakes, and there is also no benefit worth building a routine around.

Nutrition Facts labels. Two lines do most of the work. Serving size first, because everything else on the panel is per serving and a package often holds two or three. Then added sugars, which is now listed separately from total sugars — the distinction matters, because the sugar in plain yoghurt or fruit is not the sugar in a cereal. After that, look at sodium and fibre. Ignore the front of the box entirely; “made with whole grains,” “natural,” and “no high-fructose corn syrup” are marketing claims, not nutrition information.

Sugary drinks, because this is the one with the most leverage

If a family changes one thing, it should be this. Sugar-sweetened drinks — soda, sweet tea, fruit punch, sports drinks, sweetened coffee drinks — are the largest single source of added sugar in children’s diets, and unlike food they do not produce fullness, so the calories arrive without displacing anything.

• No added sugar at all under two.
• Juice: none under one; a small cup a day for toddlers and young children at most; whole fruit is better at every age.
• Sports drinks are designed for prolonged heavy exertion, which is a real thing in an Arizona summer and not what most children need after a half-hour practice. Water covers ordinary activity. There are genuine exceptions — long outdoor sessions in extreme heat, or an illness with fluid losses — and we would rather advise on those individually than write a rule that gets misapplied.
• Water as the default is easier to establish than to reverse. A child who has never had soda at home does not need it taken away.

Living in Arizona changes two things

Hydration is not a summer topic here. Dry air means fluid loss you do not notice, and children lose ground faster than adults. Water with meals, a bottle that goes everywhere, and checking that they have actually drunk it — outdoor sport in June and July needs more than any national guideline assumes.

There is no off-season for outdoor eating. Year-round activity is a genuine advantage, and it comes with year-round concession stands, weekend tournaments, and meals eaten in a car. Planning for that is more useful than pretending it does not happen: something in the bag before you leave, which is usually the difference between eating at 1pm and eating at 4pm.

About weight

Some families come to us worried about a child’s weight, and this section is deliberately short because the most useful advice is narrow.

Do not make it about weight with the child. Parental comment on a child’s body — even affectionate, even well-meant — is associated with worse outcomes, including more disordered eating and, over time, more weight gain rather than less. Talk about food and activity in terms of energy, strength, and feeling well.

Change the household, not the child. What is stocked, what is drunk, how often the family eats together, how much sleep everyone gets, and how much of the day is spent moving. These work for every child in the house and single nobody out.

Never restrict a child’s diet without a provider involved. Children are still growing, and restriction gets the growth wrong in ways that are hard to undo.

BMI percentile is a screening tool, not a diagnosis. It is one number on a chart, and what we actually watch is the trajectory across visits alongside blood pressure, activity, sleep, family history, and how the child is doing. That is a conversation at a well-child visit, not a number to read off a website.

Call us if

• Your child is not gaining weight as expected, or has dropped across growth percentiles between visits
• Food refusal comes with weight loss, gagging, choking, pain, or is narrowing to only a handful of foods
• You suspect a food allergy — and if there is any swelling of the face or lips, difficulty breathing, or vomiting after a food, that is an emergency: use epinephrine if you have it and call 911
• Your baby has severe eczema or a known egg allergy and you have not yet introduced peanut — we will make a plan rather than have you guess
• Persistent constipation, diarrhoea, or stomach pain around eating
• A teenager’s eating has become rule-bound, secretive, or driven
• Tiredness, pallor, or poor concentration that might be iron
• You are considering a restrictive or elimination diet for any reason, including a suspected intolerance
• Food is tight this month. Say so. We can point you to resources, and it changes what advice is useful — no nutrition plan works if it assumes a budget that is not there. This is a routine conversation for us and not one anyone should be embarrassed to start.

The realistic version

Nobody feeds a family perfectly. Aiming for perfect is how people give up in week three.

What changes outcomes is the default state: what is normally in the fridge, what is normally in the cup, and whether people normally eat together. Get the defaults right and the exceptions genuinely do not matter — birthday cake is not a nutrition problem, and treating it as one creates a different problem.
