So our bottle warmer kicked the bucket. M is 10 months and I thought it might be a good time try giving them to her cold since I assume we'll be giving her cold milk at 1 year. We keep bottles in the fridge but only heat them to room temp so she isn't used to having them very warm. Anyway, she is NOT happy with the chilly bottles. I keep thinking she'll get used to it but it's been a week and we're still struggling through each bottle.

Did you switch bottle temps at some point? Did you heat up whole milk at a year?
