I have a 3 month old who has slept from 230 till I woke him up at 530, he ate and played ate a little more fell back asleep at 630 for 45 minutes, then was awake for maybe an hour before passing out again. He's woken up once to eat but fell asleep during the bottle and is sleeping even when I sit him up to burp. Is that normal? Could it be caused by a growth spurt because he is eating more than usual? Could he be sick?? Sorry FTM here
