I'm desperate! Oscar around three months began to sleep great. Only waking once at night and having a couple of good naps a day. This lasted about a week and since then it has got progressively worse to the point where now at four + months he won't go down without a massive battle and at night he wakes every hour or MORE. I'm seriously going insane. We have tried all the usual things and he defied it all. Won't have a paci won't be swaddled. Won't even be cuddled or rocked to sleep. He just wants boob and then wakes up and throws a tantrum the minute I take him off. His latest is basically CIO in my arms after much screaming and thrashing he'll zonk out but them start all over if I so much as move. His ears have been checked. We've started babyrice. He's had some infant acetomenophine incase teething. Nothing is working. We have come to the conclusion that he wakes between each cycle and will no longer self settle. I find it extremaly hard to let him cry. It really gets my stomach in nots but since his defiance of all my attempts to make things as comfy and soothing and nice sleep inducing as possible. I'm completely stumped not to mention exhausted. Oh and he will bf four hours if I let him. We've got the no cry nap solution book but I was confounded to find we have aleady been doing as she suggests to no avail. Helllllpppppp!!!!! Has anyone else done ably sleep train with a baby this young. And what worked for you?
