J.P.
After camping with our niece for the first time when she was 6 mo. old, taking her to the BWC on a canoe trip- It was my experience with her that she was very entertained by just being outside. if you are willing to let him play in a little dirt:) We didn't have to bring very many toys, etc at all.
Sleeping I have less experience with, but maybe if you just try to add a few elements from your routine it will work out. Good luck!
