When your baby wakes up and wants to eat right away, trying to get a breast milk bottle warmed up quickly can be really trying – aside from the stress you might be feeling from your baby’s crying, you may also be nervous about the noise waking up your other children or other family members. Today’s question is from a reader who wants to know if there is an easy, quick way to warm a bottle at night, when you’re half asleep.

My baby is four months old, and has started sleeping longer stretches at night. I just dropped my middle of the night pumping session.
Is there an easier way to store the milk from my last pumping session of the day (around 10pm) until my baby’s first feeding at night (around 2am, sometimes a little later)? I’ve been using a cooler and warming the milk under the sink, but it seems to take a long time. Can breast milk be heated in a bottle warmer?
Yes, there is an easier way! Generally, I wouldn’t recommend warming milk by running it under water in the sink (unless you have no other option) because, as you said, it takes forever.
Here are a few other options that might work better.
Leave your freshly pumped milk out at room temperature after you pump it
Whether this will work for you depends on how long your baby usually sleeps, and how warm “room temperature” is in your house at night. Kellymom defines it as between 61 and 79 degrees Fahrenheit (16-26 degrees Celsius), and states that breast milk will be fine at these temperatures for 4-8 hours (though between 3-4 hours are ideal).
So, assuming a) your house is cooler than 80 degrees, and b) it will be less than 8 hours between when you pump the milk and when your baby will drink it, it’s fine to just put the milk on your nightstand or in your baby’s room and feed it to your baby when he wakes up.
This is the method that I used with my baby – I took a bottle up to my room after my 10pm pumping session, and my baby usually woke up around 4am to eat it. On the rare occasions that we’d both sleep until 6am or later, I would dump the milk because it had been out longer than eight hours.
That’s one disadvantage of this method – you may have to dump your milk if you and your baby don’t end up waking up for a feeding.
(Another option – a reader mentioned that she brings a small cooler to bed with her, with one bottle of fresh milk and the other refrigerated. She gives the baby the first bottle of fresh milk for the first feed, and at that time takes the other bottle out of the cooler, allowing it to warm up before the baby’s second feeding of the night.)
Use a bottle warmer to warm the milk, with everything ready to go
If using freshly pumped milk isn’t an option (if you’re using a frozen stash or are supplementing with formula), a better option than running the bottle under hot water might be prepping the bottle ahead of time and keeping it in a cooler in your room along with a bottle warmer for night feedings that’s all set up and ready to go.
Then when baby wakes up, you just have to take the bottle out, put it in the warmer, press start and bounce your baby for a minute while it warms.
If you don’t have a bottle warmer, you can microwave a bowl of hot water for 60-90 seconds and put the bottle in that for a minute or so to warm. This is less easy to do in the middle of the night – and it’s not as fast, you have to go to the kitchen, and it’s harder to juggle a baby when doing this versus pushing a button – but it’s much faster than running a bottle under warm water in the sink.
Note that you should never heat baby bottles in the microwave due to “hot spots” that could burn your baby’s mouth.
See if your baby will take cold bottles (and skip warming altogether)
Do you need to warm your baby’s bottle? No. There’s no medical reason to warm breast milk, it’s just that some babies prefer it and get used it to warm.
So you don’t need to warm your baby’s bottle if he’ll take it cold, and it will make your life way easier if you don’t have to worry about warming every bottle you give your baby and can just start feeding your milk right from the fridge.
It’s possible you’ve already tried this, but if not, give it a shot!
I would start by offering a cold bottle during the day (the middle of the night is not the time for experiments) and seeing if your baby will take it.
If your baby rejects it, you can try warming it a bit (maybe not as much as you normally would), and see if that is acceptable. If it is, you can see if gradually bringing the temperature down – until it’s not necessary to heat it at all – will work.
This won’t work for every baby – some will refuse cold milk, no matter what you do – and you may have to try this a few times under different circumstances. Try it with you offering it, with someone else offering it, when your baby is really hungry, when he’s not as hungry, etc.
