Fake Arm Baby Rocker

Anybody with kids knows exactly why today's idea would be a great one.  So you're getting the baby ready for bed and you have to rock the little stinker till he falls asleep.  Finally after hours of rocking the child settles into slumber, you gently get up from your seat and attempt to set the kid down in bed without waking him up.  If you're good they stay asleep as you slide you arms out from underneath but most of the time you end up setting them down and then patting their head/tummy/feet while they get back to sleep after waking them up in the transition.  So why not have a blanket with fake arms attached to it.  The arms would be hollow so you could stick your arms into them and hold the child.  When it came time to setting the baby down you walk directly to the crib set them down and easily slide your arms out of the fake ones.  No jostling or head bouncing drops just a quick smooth transition to dream land.
