For the past 6 months, due to a change in our living situation, we've been putting DS to sleep in his cot then bringing him in with us when he work up (usually around 3 or 4). Now we've moved we really want to get him back in his cot all night. So we've had some showdowns recently. Last night I kept resettling him in his cot when he woke but he got crosser and crosser and not coming in with us. I tried lying down next to his cot on a mattress but this just made him even angrier because he wanted me to hold him. I went to get him some milk and he went mad when I left them room, when I came back he was out of his standard-size cot and heading straight for me 
. It looks impossible for him to get out of it, although he is pretty mighty 
Any advice on getting him to sleep the night in his cot? I don't mind getting up for him but I don't want him in our bed any more because he's too big and thrashes around.
