DS will be 2 next week and is currently sleeping in a cot or in with us. He isn’t trying to climb out of his cot yet, and fits perfectly well in there. He also wants to be in with us a lot, so I worry that moving him into a cot bed will make it harder to get him to sleep on his own as he can just get up and into our room. Would it be okay to keep him in a cot until he’s a bit bigger, or does he really need to move to a real bed?.
