Putting baby down for bed

Di

Lately my babe has been screaming and crying hysterically when I put him in his crib and walk out. I put him down drowsy but as soon as I put him down he wakes up startled and screams and kicks until I return. This goes on for an hour or two before he finally falls asleep and I end up going back in so many times. I try to calm him without picking him up but it doesn’t work. some nights he’ll go down easily but most of the time it’s like this and it’s so exhausting 😓he cries so hard he chokes 😪
