Bottle-feeding can be calm and connecting, whatever's in the bottle — formula, your expressed milk, or a combination. The aim is simple: let your baby lead, go slowly, and let them tell you when they've had enough. This is often called paced bottle-feeding, and it helps prevent overfeeding, gulping, and that miserable windy, spilly aftermath.
Get comfortable first
Settle yourself somewhere supported — you might be here a while at 2am. Then:
- Hold your baby semi-upright, head higher than their tummy, cradled in the crook of your arm.
- Keep them snuggled close, facing you, so you can read their face.
- Bring the bottle to baby, rather than tipping baby back to the bottle.
Switching the side you hold your baby on partway through a feed gives both of you a little change of scene and view — a nice habit to build.
Pace the feed — keep the bottle level
The short version: hold the bottle close to horizontal, tilted just enough to keep the teat filled with milk (not air), rest the teat on your baby's lips and let them draw it in, and pause every so often so they get a breather — just as they'd naturally pause at the breast.
A feed that takes around 15–20 minutes is usually a good sign of comfortable pacing. If milk is pouring out and your baby is gulping, splaying their fingers, or milk dribbles from the corners of their mouth, slow down and check your teat isn't flowing too fast. For the full technique, step by step, see the paced bottle feeding guide.
Read your baby's cues
Responsive feeding means following your baby, not a target on the side of the bottle.
Hungry cues often come before crying: stirring, rooting, bringing hands to mouth, lip-smacking, or sucking. Crying is a late, distressed sign — try to feed before it gets there.
Full cues are just as important: turning the head away, sealing lips, slowing right down, pushing the bottle out with the tongue, relaxing the hands, or simply losing interest. When you see these, the feed is finished — even if milk is left.
Winding (burping)
Some babies swallow a little air and feel more comfortable with a wind break.
- Wind midway through and at the end, or any time your baby seems uncomfortable or fussy.
- Hold them upright against your shoulder, or sit them on your lap supporting the chin and chest, and gently pat or rub their back.
- Not every baby needs a big burp every time — if nothing comes after a few minutes, that's okay.
A little spit-up (posset) afterwards is very common. But if your baby is regularly distressed, arching, or not gaining weight, have a chat with your child-health nurse or GP.
Hygiene and leftover milk
- Wash and sterilise bottles and teats for babies under 12 months (sterilising is recommended in AU and the US for young infants).
- Test the temperature on your wrist — warm, not hot. Avoid microwaving, which creates hot spots.
- Throw away any milk left in a bottle once your baby has fed from it. Storage advice varies by region, so use these as a guide and check your local source:
| Started bottle (baby has fed from it) | General guidance |
|---|---|
| Expressed breastmilk leftover | Discard within 1–2 hours |
| Made-up formula leftover | Discard within 1 hour once feeding has begun (AU/Red Nose, NHS, and AAP/CDC all agree) |
| Freshly made formula, not yet fed | Use within ~2 hours at room temp, or refrigerate and use within 24 hours |
Once a baby has started feeding from a bottle, the 1-hour limit is the same across AU, NHS and US guidance. The longer ~2-hour window only applies to prepared formula that hasn't been fed from yet. When guidance differs, the safest choice is always the shorter time.
When to get advice
Reach out to your GP, child-health nurse, midwife, or the ABA helpline if your baby consistently refuses bottles, seems unsettled at most feeds, chokes or coughs frequently, or isn't gaining weight as expected. Get advice promptly if you notice signs of dehydration — far fewer wet nappies than usual, a dry mouth, a sunken soft spot (fontanelle), no tears when crying, or your baby being unusually floppy or hard to wake. These conversations are routine — that's what these services are there for.
Guidance here draws on Red Nose, the Australian Breastfeeding Association, the Raising Children Network, the AAP (HealthyChildren), and WHO. Regional details — especially milk storage times — can differ, so when in doubt, follow your local health service.
