Bottle feeding looks simple, until your newborn gulps, splutters, spits up or screams with wind. Most issues come from small, common habits that are easy to change. Knowing the most frequent bottle feeding mistakes helps your baby feed more comfortably and keeps every bottle safe. Here are nine to avoid.
Quick answer: bottle feeding mistakes to avoid
- Feeding flat instead of semi-upright.
- Propping the bottle or leaving your baby to feed alone.
- Making up formula incorrectly, too strong or too weak.
- Pushing your baby to finish every bottle.
9 mistakes and how to fix them
- Feeding your baby lying flat. Hold them semi-upright with the head higher than the tummy to reduce ear infections, choking and spit-up.
- Propping the bottle. This can cause choking and overfeeding. Always hold the bottle and your baby.
- Wrong formula measurements. Too much powder can cause dehydration and constipation; too little means your baby does not get enough. Use level scoops and add water first.
- Using water that is not hot enough. Make up powdered formula with water at 70°C or above to kill bacteria, then cool it.
- Heating bottles in the microwave. It creates hot spots. Stand the bottle in warm water and test on your wrist.
- Saving leftovers. Throw away milk your baby has not finished within 1 to 2 hours.
- The wrong teat flow. Too fast causes gulping and coughing; too slow causes frustration. Adjust as your baby grows.
- Pressuring your baby to finish. Follow fullness cues like turning away or slowing down. See the baby feeding schedule.
- Skipping burping. Burp halfway through and at the end of feeds.
Try paced bottle feeding
Hold the bottle fairly horizontal, let your baby draw the teat in, and tip the bottle down every few minutes to give a break. This slows the feed, reduces wind and helps babies who also breastfeed. See baby feeding positions.
Keeping bottles clean
- wash bottles and teats in hot soapy water straight after use
- sterilise all feeding equipment until at least 12 months
- replace teats that are cracked or sticky

When to talk to your doctor
- coughing, choking or colour changes during feeds
- forceful, green or bloody vomit: seek urgent help
- fewer wet nappies, poor weight gain or refusing feeds
- hard poos or straining after starting formula
Frequently asked questions
Does milk need to be warm?
No, room-temperature milk is safe if your baby accepts it. Many babies prefer it lukewarm.
How long can made-up formula be kept?
Make each feed fresh. If you must prepare ahead, cool it quickly and store in the back of the fridge for up to 24 hours.
Should I wake my baby for a bottle?
In the first weeks, your doctor may advise feeding at least every 3 hours.
