i know other factors come into play , like he much they sleep during the day and what not. i’m just curious how many times you mommas get/got up in the middle of the night. formula fed btw. also- tips for getting baby back to sleep? my LO is wide awake after feeding and i end up staying up with him for 2 hours..
