I'm grasping at straws here, but M has been taking crap naps for weeks. In the last couple of days she's been doing 2 45 min naps and one only 30 mins! This can't be enough sleep... She's only 4.5 months.

When did your baby drop the third nap, and how did you know it was time?

Alternately, any ideas why her naps are so short?????
