I say when they take enough steps to get to where they wanna go

Ashton is walking IMO. He's been walking for a couple of months. He still crawls most places when we are home because of the hard wooden floors, but if we are out where there is carpet he happily takes a lot of steps. He walked from one side of the room to the other at playgroup the other week. To me that is walking. But he will still crawl around home 90% of the time.
