my dd who is 9 months (so dont know if this helps) she usualy only falls asleep ON me, the minute i think of putting her down she wakes. sometimes i can sneak her onto the couch next to the dog, or into my bed, but thats if im lucky, i dont even make it as far as her cot, get in her bedroom door and shes up laughing!
with the boys, if i put a hot water bottle in there bed befor lying them down theyd be less likely to wake (pre-warmed so it wasnt such a shock of a cold bed..) i would do this with dd, but we never get that far!
hope this helped.
