Warm bottles vs room temp

Alesha

I’ve always made my baby room temp bottles, we feed on demand. There have only been a few times that I’ve given him warm bottles. He doesn’t seem to mind warm bottles. So my question is, is it worth it to buy either the baby breeza formula machine or the machine that just puts out warm water or should I just pre make them via a formula pitcher and use a bottle warmer? Would that make it easier to feed versus feeding on demand? I’m all about making things easier for sure lol. Pic of my little guy just because 😍😍
