12 days old and fussy lil man

So we ebf and he wants nothing but momma and to cluster feed...he has gotten to big for the bassinet so now we are in the bigger co sleeper and not sure if he is liking it 🥴 he just wants to snuggle and I'm drained!! I know I will barley remember this but yikes I don't recall the older 2 doing this..lol..but I'm thinking its a growth spurt! My uterus is killing me and these cluster feeds have my nipples dying 🥱 I know I'm making milk he has pee diapers and poop every hr, but just to make sure he has enough I'm starting lactation drinks and cookies...lol
