T.G.
It is not too young. We've been camping with all our children, even as babies. Here are some items that help:
pack and play
bug net to go over pack and play
skin so soft (bug sprays are not good for small children)
baby sun screen
a stationary activity center that he can sit in
baby stoller for walks
small toys he enjoys
first aid kit that includes infant motrin or tylenol (generic )
battery operated lantern (for night time in the tent so your hands can be free to change your son
swim diapers
I never let my kids crawl around the camp site. I entertained them in the tent (they can crawl around in there) or in the pack and play and stationary activity center. Go on walks. If there is a beach, bring some toys to play in the sand and water.
Check out the camp ground before you go so you know which sites are near the playground and such.
Camping is a great way to spend family time with no phones, tv or computers. Have a great time!
