Like many amazing discoveries, Grace realized by accident she could roll over. She likes to sccot around on her back by tossing her legs from side to side...and then...kerplunk! Hayden was so excited.
I don't think Grace was as impressed. At first she just started at her mat in disbelief.
Once she realized she could lift her head up and look around she was much proder of her accomplishment...until she realized she was stuck that way and didn't know how to scoot around the way she can on her back.
I don't think she has any idea how it happened, or any inclination to try for a repeat performance. Still...the girl has rolled.
