7mo, standing up and co-sleeping.

[Iamjustthemilkmachine]

I've co-slept since day one, have got a side cot but never actually get to put ds in it, now he's 7 months he's started pulling himself up and being very proactive at jumping head first off the bed (which is low), but I don't want this to continue. Please help me think how can I transition from cuddling to me all night to being in the side cot, and then in the cot with the matress low so the sides stop him from scaping, or what other solutions do you see to his mobility at night and at naps (the problem is only when he's asleep but I'm not yet in bed, not actually during the nightime).
Thanks!
