Notice how she's so involved with her toys, and how they're not moving forward, but she is.
Her head keeps going lower and lower - until she does a face plant!
Notice the size of the slobber spot on the sofa grow throughout the maneuver!
Wait for it...
...wait for it...
Ugh! Face plant!
"Look Mom, I did it!"
Only problem is, she hates being on her stomach. She gets a frustrated look on her face and grunts like a pig.
Not bad for 4 months, huh?
