what age do they stop napping?

[moljam]

dc 3 is 18 months and doesnt always seem to want to nap.he doesnt sleep well at night either.i cant remember with first 2 dc how old they were when they stopped napping.

my dd was just under 3 when she stopped. My sisters ds still has a sleep most days at the age of 4 (he takes himself to bed or falls asleep on the couch!!)
