How much sleep does your child need

According to one of the newsletters I received from BabyCentre, 11 hours at night and then two naps totalling more than 3 hours:

Age  -  Nighttime Sleep  -  Daytime Sleep  -  Total Sleep


1 month - 8 - 8 (inconsistent)  -  16
3 months  -  10  -  5 (3)  -  15
6 months   -   11  -   3 1/4 (2)   -   14 1/4
9 months   -   11  -   3 (2)   -   14
12 months  -  11 1/4   -   2 1/2 (2)   -   13 3/4
18 months  -  11 1/4   -   2 1/4 (1)   -   13 1/2
2 years   -   11   -   2 (1)   -   13
3 years   -   10 1/2   -   1 1/2   -   (1)12
*Note: number of naps in parentheses

I would say she sleeps 1.5 - 2.5 hours in a day, and probably 13-14 over night. So we're not doing too badly, I guess!
