Interesting. Not ideal if it’s a full on fast. It would be difficult to fast on liquid as dehydration may reduce milk supply unless if your goal is to try mixed or bottle feeding. If fasting is necessary due to religious requirements, best to consult your pediatrician.

I fast but I only started with 10 hours.. and I make sure to eat all 2500 calories in the hours I eat. I am at 13 fasting now. I eat a lot still Idk if you mean for just x hours

Yes
