HA! Who knew?! We just installed them this morning. LO stared at the fan to fall asleep for napping, then when he woke up I let him have some quiet time (as usual), and he stared at it again and went down right away for a 2nd hour of napping (very unusual for him to nap again after a 1 hour nap). So, there you go, add 'ceiling fan' to your baby shopping!
