If I were a "tweeter", I would tweet this: my daughter has been taking a nap since 8:30am. It's 4:00pm. that's a 7.5 hour nap. I've checked on her twice to make sure she's okay and each time she's been in a new sleeping position. maybe she is growing.
as a general rule, she is awake for 2-3 hours and then goes to sleep. It's like she's reverting to her infant days.
...maybe I should ask my dr. brother if I should be worried...but I really think she is okay, she's not lethargic or anything during the day. she plays and plays, she eats and eats, and is a super happy kiddo.
ah-ha -- it's like she knew I was talking about her...there she is now crying her little wake-up cry. I love her.
