Hi guys need some advise.

My almost 6 week old is a terrible sleeper and at night would wake every hour, I would change him, breast feed him and he’d fall asleep at my boob and wake up again an hour later. Putting him on the boob was the easiest way to get him back to sleep and for me also. My supply is starting to dry up due to I guess me not eating and drinking enough throughout the day bcos it’s hard to even put him down long enough for me to make myself something decent. Ps he’s an even worse sleeper during the day! I’m worried now that if I have to switch to formula how am I suppose to settle him back to sleep at night every hour if I can’t feed him so often like with breast milk- guide lines say formula every 2-4hours.
