my 5 month old will nap in his crib fine. i can put him to sleep drowsy and he will fall asleep but he wakes at least 5 times a night. even if he is fed and diaper is changed he will cry and scream until someone holds him. ive tried white noise, ive done consoling and checking on him, ive held his sleep sack so it smells like me, he doesnt take a pacifier to soothe and now ive tried cio. after an hour hes still crying. nothing i do will stop him from crying unless i hold him then he falls asleep in like 2 minutes. any tips?
