Woopster- we can't be sure, unless dh or I sleep walk, but I doubt it.
Skatty- he tries to climb in the day, but isn't really successful, or we don't allow him to do it much (tries to climb into his walker, type he can sit in, but I usually pick him up and put him in once I see him trying to get in it. He climbs in and out of his buggy too, up and down the stairs -monitored by us. Other than that I'll need to ask the childminder if he climbs much in the day.
Just to say his cot is quite large and deep, size of a play pen. When he stands in it, the top is at his shoulder level.
