So I received a bottle warner at my baby shower which I love for the obvious, BUT my question is. Is it really necessary to warm up a bottle in the middle of the night? I have and I want to continue but my newborn gets so mad and wants everything fast that really there isn't any time to warm it up lol. Is it that bad to just give her room temperature formula? I mean thE hospital gave us room temperature ready formula bottles! What do you guys think?? Please help. Is it bad to give her room temperature formula or should I warm it up (water first of course)???
