Is he feeding all night or jsut comfort sucking. My DD wanted to be on the BB from about 6pm til midnight but wasn't hungry just wanted comfort. I ended up giving her a dummy as my BB were in a delicate state. (they were torn and bleeding and i ended up with thrush in both nipples) If you DS does not have a dummy it may be worth a try but it depends if you want him to have one or not. I originally didn't want my DD to have one but gave in and with no 2 on the way i have decided if she too is a comfort sucker than i dont mind if she has a dummy either. HTH.
