I have tented with a little one. Humidity at night? Baby doesn't sleep. Bugs at night? Baby doesn't sleep. Baby gets bug bit all day? Baby doesn't sleep at night. Teething? Baby doesn't sleep? When does baby sleep? When mommy/daddy are carrying the little one in the pack. It's how I used to get my exercise and have my son take a nap when he was that age. I've tented with a little one, 4 years old, after he spent all day wandering the woods. He slept. Mostly. I hope it goes better for them. And I'm glad they won't be near me when I am on the trail.
