Hi Clare, Seb has been in his bed for about six weeks now. We have a normal cotbed and little pillow set from John Lewis, the duvet is 7tog. His duvet set has dinosuars on it, he is very excited by it on a daily basis as you can imagine...until the one with trains comes out and then he just about loses it. We don't have any bedguards on the sides, he has fallen out a few times but like you said, they live, they learn.Nowadays we hear 'Oh NO! Seb out, seb OUT!' and we go in, and say 'Get back into bed with your teddies, Seb' and he does. We do have a normal sized single duvet on the floor to 'soften' any falling out though.
