For the past 4 months my son has been sleeping through the night in his crib but for the past couple weeks he wakes up screaming in the middle of the night and can’t calm himself down. Some nights I try to let himself cry himself back to sleep and other nights he won’t. I have to try to give him the bottle and calm him down but that doesn’t even work sometimes :/ my son has been up crying for the past hour and idk what to do! His diaper is changed, he’s has a bottle, and I’ve tried to help him calm down. None of it is working.
