My DD is 19 months old and has been using the Samsonite Bubble travel cot until now. She now rolls too hard and the whole thing moves with her so I need to put her in something else. I borrowed my friends Baby Weavers travel cot which she slept in and was going to buy one, but I note that it says only suitable until they can stand up. What on earth do you put them in until they are ready for a bed? Is there a travel cot that lasts longer.
