3 month old new habits

Tina

So all day yesterday, my son did great. He took a 3 hour nap two days in a row. One day was in his play pin and yesterday was on the couch. I don’t hold him while he sleeps. I put him down. All of a sudden last night, he refused to sleep unless in my arms. Everytime id put him down, he’s wake up screaming . I tried to help sooth him, at one point I even tried to see if he would cry it out. But he just kept screaming louder and louder. The second I pick him up, he stops crying and falls back asleep instantly. We did this all night. So obviously I didn’t get any sleep at all. I really hope this is only a one time thing. He used to sleep all night no problem. I’m exhausted.
