Kid4 is almost 5 months old. In the past few weeks she has absolutely mastered rolling from back to tummy, but still had some trouble with tummy to back.
Today I set her on a blanket on the floor with some toys, so she could play. I left the room for a few minutes while Kid2 was sitting next to her playing the wii, to put away a load of laundry. I came back and Kid4 was nowhere to be seen.
I asked Kid2 if he'd moved her, and he said no. Then we heard her.
She had rolled under the coffee table and was happily chewing on a shoe.
Uh oh! Guess we better get back in the habit of babyproofing, STAT.
