I agree that 2 naps is the usual for a 10 month old but I know of babies who took one. I always watched for signs of tiredness......rubbing eyes, yawns, fussiness, becoming clinging, etc. Then we had a set sleep time routine that we always did. Change diaper, lower shades, turn out lights, cuddling, soft music, rocking...........whatever you do as your routine.
The little boy I take care of was up for about 3-4 hours at this age before he showed signs of being tired with rubbing his eyes and yawning, etc. He soon started taking one nap, though, and that started when he would just play in his crib when his mom tried the second nap. Hope this was of some help.
