So I’ve been super blessed with a baby that sleeps so well. I’ve been able to lay him down at night awake and he’ll put himself to sleep. Recently he’s been really fussy during the day fighting sleep. Last night he went down ok and slept but then woke up at 3 and hasn’t let me put him down since. He’s never like that. I’m not sure what is going on. Should I be worried he might be getting sick? Or just chock it up to I had a good 7 weeks of being lucky lol
