My baby boy is 10 weeks old and for the last few day he has not slept more than an hour with out fussing and crying. He fights his sleep horribly when its time to go down for the night and screams his head off. He used to wake up ever 3-3.5 hours would eat around 4 oz and then go back to sleep.  New hes up every hour fussing and crying. Idk what to do. Ive tried swaddling which he usually sleeps in, white noise, baths, swing which he used to sleep in fine, lullaby nothing is working. Idk what else to do and why his sleep is all messed up all of a sudden. Please help
