Baby bottle warming -- microwave

[Anonymous]

The only statement of caution in the instructions for the bottle type we're using (Dr. Brown's) is that microwaving may create hotspots in the liquid. At first, we were heating the bottles (for formula) indirectly, by placing into a vessel holding boiled water. Then we tried the microwave, and no surprise that it heats the fluid very quickly. For other plastic bottle users, do you also use the microwave? I have some worry that we used to do it perhaps the safer way, but I do hope that microwave heating (for formula only; for breast milk I have read that microwaving may break down proteins) is not causing any harm (either to the liquid itself or indirectly, by affecting the bottle integrity somehow).

Because of hot spots, you are not supposed to heat either formula or BM in the microwave.

Don't microwave. We put the bottle in a cup of not water.

OP here -- for the hotspots concern, I would wait, and gently swish around, to dissipate any possible such spots. Again, I am curious if others do microwave, and have not had issues.

Why heat it? Just give to baby at room temp.

OP here -- she seems to enjoy the heating, but we could try room temperature. So the main mode still is to heat a bit at least.

I don't know if it affects the chemistry of the fomula, but I don't think it will impact the bottle. We used a microwave bottle sterilizer, and I can't see how heating milk in the microwave would be any different in terms of how it affects the bottle.

If you haven't tried room temp yet, though, I would advise trying it. DD didn't seem to distinguish room temp from heated at all, and it was so much easier!

don't do it!!

Buy a big wide-mouthed mug. Fill the mug about 2/3 with water and heat it in the microwave till the water is pretty hot. Then put the bottle in the mug for a couple minutes, then shake before testing and serving.

Bottle warmer or room temperature.

I microwave my bottles.

4oz. 15 seconds

6oz. 20 seconds

8oz. 28 seconds

I then swish them around a little before I give to baby.

We started microwaving milk for dippy cups. We know the time. No problem but I'd be more scared w fluctuating volumes!

Plastic in the microwave? Yikes. We used a bottle warmer. Worth it.

[Anonymous]

I don't put plastic in the microwave for any food. Would never for a baby bottle. We used a warmer, putting the bottle in a glass of hot water, or we heated in the microwave in a glass measuring cup, swished around and then transferred to the bottle.

Why can't you microwave plastic? If it can be submerged in boiling water for sterilization, why can't it be microwaved?

Because most people don't understand physics or chemistry.
