Bit of a silly question, but my 2 year old son kept climbing out of his port cot when out at friends/family - since then we have transferred him to his big boy bed - he roams around his bedroom a little but sleeps well in bed. Any suggestions for when we are out? I think he would just keep climbing out of port cot if we tried him back in there, and a bit worried about putting him on a bed because he moves alot during his sleep, he does 360 turns and will eventually fall off. So I supposed only other option is mattress on floor? Either way he'd be roaming the room so it would have to be kid safe - which not everyone's rooms are.. any ideas? Thank you!!
