unlatching all the time?

Andrea

So my 10 week old has always been a great latcher and we haven't really had problems breastfeeding. typically at night he'll nurse himself to sleep and that's kind of been our routine and I'm okay with that. the last few nights though when it's time for his night nursing, he'll eat just fine on one side and get a little drowsy, then i switch sides like normal and he eats fine for 10 minutes then starts unlatching. he acts almost mad if i try to relatch him (he typically feeds for 15-20 minutes each side so I feel like 10 minutes might not be enough) so ive stopped trying to relatch him. anyways I'm wondering if this is normal? growth spurt maybe? Idk I'm just stressed cuz he has always nursed himself to sleep and now the last few nights he fights it and I worry he's not getting enough nursing or something and that's why he acts frustrated?
