What is the typical sleep habits for twenty-four month old babies?

Baby aleep. They will still require a daytime nap, about one hour or so. They will also still sleep about 10-12 hours at night. Not much different than 1year olds but they definitely should be sleeping through the night on their own and in their own bed.
Bedtime ritual. Your toddler may climb out of the a crib at this age. The crib mattress may be placed on the floor or platform in a corner as a transitional bed. A simple roll bar can be made from plywood or purchased at a home products outlet. Your bedtime ritual at this age may need to be more involved to settle a child that may want to leave the bed and wander the house. Bedtime stories are favored.
