DD24 mos. defaults to exactly 11 hours of sleep in a 24 hour period, however we want to divide it up. I usually opt for at least a one hour nap because I need a break! She wakes several times per night. Exercise or other forms of stimulation do not make her more tired.

As a newborn she did not sleep much and was bored and irritated she couldn't move around herself. I swear I was the only mother celebrating getting a *break* when DD started crawling and then walking. lol
