My baby is 5 weeks and sleeps so well when holding him into a sleep mode once I put him down for about 15 mins he gets so startle easily and then wakes up crying... I'm still trying to figure this out and is has been going on for a week now... Doctor says he fine but he wakes up so upset sighs I haven't slept in a week maybe a two hours each day and I feel so sad because my baby can't sleep ... I've tried almost everything that's been suggested... I'm trying to comfort him not I. Such myself falling asleep on him because I'm so tired and My mom is home she helps me out other then that I'm alone and it's so hard.
