What to do??

Stevie

So I have 3 month old twins that I ebf and they are cluster feeders throughout the entire day but at night I will dream feed them around 11-12pm and then they won’t usually eat again until 4-5 hours later. I know I’m supposed to feed them on demand if not every 2-3 hours at this point but with a 2 year old and my twins I’m exhausted and sometimes don’t wake up until they start getting fussy to eat and sometimes I even have to wake them up to eat during the night so my question is is it bad to let them go that long without eating?? My first baby would sleep the entire night and I talked to my doctor about it and she said I definitely needed to be waking her up every 2 hours to feed.l
