For about the last 4 months my now 19 month old DD has been refusing to nap on the weekends though she naps every day, sometimes twice/day for her nanny, no problem. She sleeps about 12 hours at night and is a champ so my gut tells me not to worry about it but it's just bizarre and I'm curious if anyone else has had this experience. She is totally pleasant despite missing naps on the weekends but I know she's tired because she'll always snooze if she's in the car/stroller for more than 10-15 minutes. Also I find myself looking forward to bedtime which I feel really guilty about! Is this a phase or is this long term?
