DS is 33 mos. old and lately has been sleeping A LOT. 10-11 hours at night is the norm, plus a 1 1/2 or 2 hour nap during the day. For the past week or so, he's been sleeping the same amount at night, but taking LONG 2 1/2 to 3 hour naps during the day, for a total of 12 1/2 to 14 hours of sleep during a 24 hour period. No other issues, no behavior changes, lots of energy.
