Just interested in opinions on this. Some friends of ours have a camper van and often go away to campsites etc. They happened to mention casually to DH that their son sometimes sleeps in it overnight when they're at home as a little adventure. Fair enough, but he's only 3 (well, 4 in October). The camper van is parked on their drive and I presume it's locked but I don't know if he's in it on his own or whether one of them sleeps with him.
What do you people think? I would have thought 3 1/2 to be a little young for this but I may be being over the top!
