Nap time consolidation

Looks like you've gone down from the initial "perpetually all day" sleeping pattern to the 4, then 3, then 2 and now 1 nap a day. In the past 2 days, you haven't really had your morning nap, and it doesn't seem to bother you very much. When you DO finally take your nap, though, you have slept for 2 hours compared to your usual 1/2 hour stints.

What to make of this .... part of the maturation process ?

Just as long as you get enough rest, child. :)
