Formula feeding, without the guilt

Choosing a formula

All infant formula sold in the EU must meet the same strict nutritional rules, so the cheapest supermarket tin is nutritionally complete. Price mostly reflects brand and extras.

• Stage 1 / first infant milk is suitable from birth to 12 months. There is no need to move to "follow-on" milk at 6 months.
• Hungry baby, anti-reflux, comfort and HA formulas are only worth trying on advice from your BVC nurse or doctor.
• Specialist milks for cow's-milk protein allergy are prescribed, not self-selected.
• Plant milks (oat, almond, rice) are never a substitute for infant formula.

Making a bottle safely

1. Wash your hands and clean, sterilised bottles (sterilise for the first 6 months).
2. Boil fresh water and let it cool — powder is not sterile, so hot water matters.
3. Pour the water in first, then add the exact number of level scoops.
4. Never add extra powder or extra water — the ratio on the tin is the safe one.
5. Shake, then cool under a running tap and test on your wrist: lukewarm, not warm.
6. Throw away anything left over two hours after a feed starts.

Make bottles fresh when you can. If you must prepare ahead, cool quickly, keep at the back of the fridge and use within 24 hours. Never reheat in a microwave — it makes hot spots.

How much and how often

A rough guide after the first week is about 150 ml per kilo of body weight per 24 hours, split across feeds. In practice:

• First week: small amounts, 8–12 feeds a day, following the tin's newborn guidance.
• 1–2 months: roughly 90–120 ml every 3–4 hours.
• 3–5 months: roughly 120–180 ml, 5–6 times a day.
• 6 months+: milk continues alongside solids, gradually reducing in volume.

Follow the baby, not the number. Steady weight gain, enough wet nappies and a content baby after feeds matter more than finishing the bottle.

Combination feeding

Mixing breast and formula works well for many families. If you want to protect your milk supply, introduce formula gradually — one feed at a time, a few days apart — and keep breastfeeding or pumping at night.

Dropping feeds suddenly can cause engorgement and blocked ducts, so go slowly for your own comfort too.

Little things that help

• Paced feeding: hold baby upright, keep the bottle horizontal, pause often.
• Slow-flow teats to start; change size only if feeds get frustrating or very long.
• Keep skin-to-skin and eye contact at feeds — bonding is not about the milk source.
• Share night feeds; this is one real advantage of the bottle, so use it.

Ask your BVC nurse if you are unsure about amounts, reflux, constipation or a suspected allergy, or call 1177 for advice.
