I'm very happy (and lucky) to be able to say that my daughters still (at age 4) are nappers. This was a hard fought battle...
Once they got on a good sleeping schedule (at about 3 months) they took 3 naps a day (don't be too jealous, these naps were less than 30 minutes each!) Before they were 6 months old, it had dropped to 2 less than 30 minute naps a day. Once they turned 1, the morning nap was tricky... If they took an am cat nap (about 15 minutes before 9), i could get 30 minutes in the afternoon. If that catnap happened after 10 am, i could kiss the afternoon nap goodbye and say hello to long afternoon.
A friend told me to hang in with the naps as her daughter had become a better napper with age... As an adult, i am not know for my napping, but my mom told me that i napped until i was 5 1/2 and started pm kindergarten. My husband is a terrific napper and can practically fall asleep on command. The girls have good napping genes, it just took time for them to surface...
After age 1, the morning nap mostly disappeared, but the afternoon nap started to last more than 30 minutes... After the girls turned 2, i could count on almost 45 minutes... At 2 3/4 they caught bronchitis. They took some really long naps and just stuck with it (the naps, not the bronchitis). Now at age 4, i can count on at least 1 1/2 hour naps, 2+ if they had a super active morning. These days it's just getting them to sleep that is the tough part...
As they share a room, the girls like to share books and talk while falling asleep. I usually have to go in 2 or three times to quiet them down, and then they will fall asleep. Sometimes, they will hear me opening the door and throw themselves down on the pillow and feign sleep...
I just checked on them... I have one asleep and one with her hands clamped over her eyes. I don't think she wants me to know that she's still awake! ;)
