Thanks for all the replies. I think we might try in a month or two and convert the cot to a toddler bed and see how we go. He is going to sleep without too much fan fare at the moment so hopefully he will transition well. I need the cot probably by December as Lachy grew out of the basinette at about two months so i expect this one to grow out quickly too. Do you think an 18 month old will get the excitement of choosing his own big boy bed linen etc or is that just silly at that age?
