You are not a failure at all! My DD2 only wanted to be strapped to me at all times for the first 6 weeks. A hugabub sling saved my sanity! I was able to walk around and do things. The first few weeks is very unsettling for a baby - suddenly they are out in the big wide world and evrything is strange. They are used to being snuggled up tight inside mum hearing her heart beat. By using a sling and having him hear your heartbeat would comfort him.

You are also probably suffering some Post Traumatic Stress from his birth which is also understandable. Can you get DH to hold him and walk with him while you have a nap or get some rest. You need this to heal and it is important you can get this time. Even a friend or someone who can just come over for an hour or so?
