It's a good thing I planned our tear with provisions for a bunk over our knees because we're having a baby this summer.
The bunk I'd planned might not be suitable for a while since I've read little kids need a proper mattress. I'm thinking I'll take the doors off one of our large foot cabinets (~30x15x14"?) and cut down a crib mattress to fit in there for the first 12-18 months.
I'm thinking a curtain to segregate the bunk from the rest of the cabin would be good for nap time, it already has nightlights in the ceiling in that area. The 12v outlets in the cabin are switched so little fingers shouldn't be able to get into trouble with those for a while, and the 120v outlets are tamper-resistant.
Beyond electricity and sleeping arrangements, what other important concerns are there for a little camper in a tiny camper?
