There are milestones and there are meterstones. Not quite a mile, but still moving forward, one meter at a time.
So here are some of our meterstones:
reaching to sides when on belly
lifting arms when on belly
superman flying pose
brings knees up/side when on belly
reaches up when on belly
moves in a half circle (both sides) when on belly
Puts some weight on feet when supported
does high five
As a PS - If you love those hats as much as I do (thanks Jill for the site) check out http://www.petalbabies.com/
Katheryn is actually wearing Nick's hat - she kept taking his off and trying to put her purple one on him!
