firstly congratulations on the birth of your son

As Saffi said it gets better. Just enjoy these early days. If he sleeps on you then take that opportunity to rest and just watch a movie ect.. Or alternatively lay on the bed with him while he is snuggled close. Once he falls asleep then slowly get up and get some much neded time out for yourself.

my DD was like that, she just wanted to sleep on me day and night. She wouldn't even settle for Dh but around 3-5 weeks it worked itself out..

Good Luck..
