My son has been a great sleeper since about 8 weeks. He sleeps through the night from 7:30pm to 7am. However, this past week has been a nightmare! It’s either one of two things. First, he looses his paci and screams bloody murder until we come put it back in for him, and then he repeats this almost every hour throughout the night. The second thing he does is rolls into his tummy and gets frustrated and starts screaming. He know how to roll from his tummy to back but won’t do it. I’m at my wits end, we got so spoiled with nearly 12 straight hours of sleep and now it’s like we’re getting up every hour! Any tips?!
