My baby turned 8 weeks yesterday (Yay, kinda)... He's been fussy since early morning. He slept from 2am to 5am and then he woke up every 1hr and 1/2 after that and it was hard to get him back to sleep each time. He's drooling a lot, and spitting up his formula even though he's not eating as much as usual. He hasn't slept for more than an hour ALL day when he usually takes three hour naps. What could it be? My parents think he's teething. He doesn't want a teething ring. Growth spurt maybe? Anyone else experiencing this🙁
