Sleep in Numbers

I feel like I'm constantly trying to figure out the appropriate amount of sleep my daughter should be getting.  Found this great (and may I add uncomplicated) sleep chart organized by age on Parents.com.  I love the chart because it gives ranges and not just one number.  Not every baby will need the same amount of sleep, but it's good to know around where they should be.

Age	Total Sleep (hours)	Nighttime Sleep(hours)	Naps (hours)
Newborn-2 months	16-18	8-9	7-9 (3-5 naps)
2-4 months	14-16	9-10	4-5 (3 naps)
4-6 months	14-15	10	4-5 (2-3 naps)
6-9 months	14	10-11	3-4 (2 naps)
9-12 months	14	10-12	2-3 (2 naps)
12-18 months	13-14	11-12	2-3 (1-2 naps)
18 months - 2 years	13-14	11	2 (1 nap)
2-3 years	12-14	10-11	1-2 (1 nap)
3-5 years	11-13	[10-11] 10-13	0-1 (naps usually stop by age 5)
