We took our boy camping when he was eight or nine months old. (I blogged about it here.). He was crawling, but we didn't want him crawling around in the dirt — our campsite didn't have much grass, only rocky dirt. Between being cooped up in the car seat for the drive to the campground, and then not being allowed to move around on his own, my son refused to go to sleep! He hadn't had a chance to get rid of any energy and was too keyed up. My husband and I decided we should have brought his Jumperoo so he would have gotten to move around. An odd piece of camping equipment, to be sure, but ….
We also thought the Pack N Play would have been handy. We had planned on letting him sleep on our queen-size air mattress, but didn't count on it not staying inflated well enough, so it rolled him around every time he moved. It was a very long night.
This camping tip reminded me of my son's first experience camping. He was a crawler at the time (and FILTHY because of it), and, even though we managed to shove the portacrib into the tent, he barely slept. Then, there was a freak snowfall the next morning. It was a long two days, let me tell you.
