Well, it's more accurately described as an army/inch-worm belly scoot/wiggle, but she can get from one place to another pretty well while doing it. She's been working toward this for a while, going from scooting backward to doing a swan dive face first in the carpet while tucking her knees and sticking her butt in the air. She can get up on all fours in a typical crawling position but doesn't quite know how to push off from her feet to propel herself forward. The one thing she has down is that she's GREAT at pulling with her arms. She's going to have some major arm muscles pretty soon :) Anyway, it's a huge milestone that I hope will make her happier as she's been a little cranky for the past couple of days.
Here are some pictures of Lucy "exploring" the area under her bouncer: :
Here are some from outside later that day:
And Maryn has been camera-shy lately (she won't even let me bribe her for pictures anymore!) but here are a couple of her in art-mode.
