How old is your LO and how can you tell when they're ready for a nap? I used to go by the 1.5 hour awake rule and it worked beautifully! That, and if he was fussy over everything I tried to do, I'd just put him down and shortly afterward, he would fall asleep with little fussing. I occasionally supplemented that rule with cues such as yawning, eye-rubbing, a bleary look in his eyes, but now at 6 months old, the cues have been lessening and he seems to need to go longer between naps. Even if I wait longer for his nap and he seems fussy, I would put him down in his crib and he would just fuss or coo around for 20+ minutes before falling asleep! I miss when I was able to tell definitively! =/
