Dd is 7 months old and has always resisted sleeping - right now she is in her crib crying and has been steadily for 30 min. She probably does this about twice a week. We watch for sleep signs and do the same routine, but sometimes she cries non-stop for 45-60 min until she passes out. Going in to check on her / pat her back definitely makes it worse and prolongs the crying, so we usually let her cry.

My question is - how often do/did other babies cry like that? I thought once we did sleep training / CIO we wouldn't have to keep having her cry multiple times a week.
