Bonnie is the same But she is getting much better with a bit of training. I told someone once about it and they said maybe get a dummy... but there is no way!! If they sleep well at night I would hate for that to become disturbed by the want of a dummy... anyway.
Do you wrap him? Maybe it would be easier to put him down if he is wrapped? I found that using one of those little sleeping bags works too.. rock them to sleep in it and put them in bed in it.... that worked once. Also if you have one of those cocoons... put him in it and use the handles to gently swing and rock it then when he is asleep put it down. If he stirs, just do it again without picking him up

Good luck and let us know how you go!!
