Please help with ideas, I am starting to get soooo frustrated!

Though I am thrilled that ds is starting to get around and is pulling up on everything I just can't seem to get him to sleep anymore! I have always put him down awake in his cot and left him to do his own thing, but now I have up to an hour of him pulling himself up and then screaming cos he is stuck!

My only strategy so far has been to go in there and lie him back down each time, trying not to interact with him. I usually give him a minute or so to see if he can sort himself out, but he doesn't seem to be able too.

After an hour I am so over it I just get him back up again, and usually let him fall asleep in the pram or car, but because we are moving I desperately need these sleep times to pack!

Help????
