This is not really helpful advice, but a funny story.
It was in Crater Lake, Or. at the end of the season. In fact, the campground closed the day we left.
We had brought my first born on his first camping trip at 10 months old. Bless him, he was really into this new trick he'd just mastered, crawling. It was already cold, so we went to the tent early.
Or tried to. This was the coolest thing Baby #1 had ever had happen to him, you'd think. Both parents in this tiny little room on the floor with him. He was not the least bit sleepy at his normal bed time. Or two hours later! He just kept wiggling out of that cute little baby sleeping bag and crawling around and around the edge of the tent. Over our feet, around, over our heads, around, capture and return, escape, giggle and crawl some more.
We were just grateful for no crying, I guess.
