who else's 3 month old suddenly became so fussy and sleepless at night?

He's always been a good sleeper so I'm thankful for that. but I definitely have a little diva boy

@jgled000, I hope it goes better for me too! my son has been fussy throughout the day unless he's sleeping and at night he wakes up alot.

mine is usually up for 1.5-2 hours max at any time. last night he was up for 2.5 hours and was crying uncontrollably. nothing could calm him down. he finally exhausted himself amd passed out at 9 and slept until 4am. I hope tonight goes better!
