Hi all,
smackapacca, we have been camping in our camper van since DS was 3.5 weeks old. He is now nearly 3.
We started off with a Koo-di pop up bassinette for about £20 which fitted on the floor area of the camper.
When when he outgrew that he went in to a NScessity Large Pop Up UV Tent, about £63, which he goes in in the pop top part of the camper. Since it has two zips - an inner and outer - he would have to be an extremely bright 18-24 month boy to unzip both before I had heard him and got up to him (he did it eventually, thankfully in a hotel, rather than the top of the camper, but even if he had it is highly unlikely he would just have launched himself down! Plus I had heard him trying to do it and was waiting for him!).
We put one zip one side and one the other. You only need to unzip one to check on them in the night (the second flap is the mozzie one).
It is very handy as it doubles as a play tent and a UV tent for the beach.
We never had a stair gate on his room - tell a lie - we did for 24 hours - he launched himself over the top of it in frustration at being trapped and nearly broke his neck! There followed 2 months of hell trying to keep him in his own bed! We tried rewards, threats, holding the door closed, etc. you name it! But eventually something just clicked and he stays there now.
So for camping this year - starting Easter - we have just been to buy him a junior sleeping bag. He got to chose it and try it in the camping shop :) And he will sleep up top again with a bed guard to prevent him rolling down and there will be a ladder should he wish to climb down (he is a VERY experienced climber!).
So my advice would be the tent option, otherwise just persevere with the airbed, since the inner tent bedroom is like a tent for them anyway. I always put a few toys in there and a torch so he can see in the dark if he feels the need.
We too bought a ready bed. Thankfully in the sale, but even so it has been used for just half a night! DS didn't take to it at all. I'd get a baby sleeping bag instead, which should be more than warm enough, on top of your air bed.
Now we set a boundary we feel is realistic for all - if he doesn't want to go straight to sleep he is allowed to play, but is not allowed to leave the room/area where he is sleeping, which, touch wood, seems to be working.
Sorry for the ramble but no short way of explaining it all!
