Sleeping in swing (repeat from Oct. 2011)

sytom

My daughter has it all, crib, cradle, bassinet.  Except at night, she doesn't seem to be able to sleep in any of those.  Right now, she is asleep on the couch next to me.  It's like she doesn't want to miss any of the action.  Most days, she falls asleep in her swing (Fisher-Price My little lamb cradle'n swing).  Is it really bad to let her sleep in it for a few hours?

TIA!
