The short answer
In the UK, pasteurised whole or semi-skimmed cow’s milk can be a main drink; semi-skimmed may suit children over 2 who eat well and grow normally. Skimmed and 1% milk should not be a main drink before age 5. Count yoghurt and cheese too, and ask a health professional about a milk alternative or a child’s growth.

Keep in mind
- Offer milk as part of meals rather than a drink to carry and sip all day.
- Count yoghurt and cheese in the overall dairy pattern; more milk is not always better.
- Milk after brushing or at sleep onset can raise tooth-decay risk; offer water overnight.
How can you tell if milk is crowding out food?
Review the overall pattern if your child fills up on milk, regularly refuses meals, eats few iron-rich foods or has worsening constipation. One small meal is less important than several weeks of eating and growth.
When and how can you offer milk?
Offer milk in a cup, preferably with a meal, and water when your child is thirsty between meals. Sipping from a bottle or cup all day, or falling asleep with milk, can affect appetite and dental health. An open or straw cup is fine if used safely.
How do you choose the milk-fat level?
UK guidance allows pasteurised whole or semi-skimmed milk after 12 months; children over 2 who eat well and are growing normally may have semi-skimmed milk. Skimmed and 1% milk should not be a main drink before age 5. Check with a health professional if your child has growth or health concerns.
Can plant-based drinks replace milk?
Plant-based drinks differ in protein, energy and nutrients; not every product is nutritionally equivalent to cow’s milk. If changing because of allergy, vegan eating or another reason, choose an appropriate fortified option with a clinician or dietitian. Do not give rice drinks to children under 5.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Confirmed weight loss, a marked growth-chart change or persistent poor appetite.
- Paleness, marked tiredness, very limited food variety or concern about iron deficiency.
- Repeated coughing, pain, vomiting or difficulty swallowing when drinking milk.
