crawling around the cot

[janx]

my v lively 10month old dd has discovered how to pull herself up in the cot and now it is so difficult to get her to lie down - especially for her daytime nap. She can't get herself back down and cries, but when I put her back down, she immediately does it again. She is tired when I put her down and really needs a sleep, but just loves crawling and standing up - any tips?

DS does this i put him in a growbag/sleepnig bag and he cant get up - cruel i know but it works

Sleeping bag may restrict her movement?

She is in a sleeping bag and I even tuck the end bit underneath the mattress - but she is a little hodini and can wriggle out of anything!
