Napping

Libby used to love to sleep..now she hates it. She is still an angel at night and falls asleep on her own (99% of the time)...but lately she either rarely naps, never naps, or takes an extended nap during the day. Over the weekend she was taking 90 minute naps consistently from 9-10:30AM. It was wonderful - for her and me. Now the daycare tells me today she hasn't napped (as of 1PM). This means we will have a very cranky baby tonight. Joy! What are you supposed to do that? You can't force them to sleep.
