I'm just curious because up until a couple of weeks ago DD could stay awake for about 2 - 2/12 hours before going down for sleep. Now she can last at the most 1 1/2 hrs but usually 1 hr when she is showing tired signs. Is this normal? I don't mind putting her down cause I like to watch her signs so she doesn't get overtired but still... seems like a short time - i thought it was meant to get longer?
