Confusion about "W sitting"

My 13 month old sits in the "W" position a lot--when she's doing something like looking at a book or playing with toys on the floor, I'd say she W sits at least 50% of the time. She seems to prefer it because it makes the transition into crawling a little easier--all she has to do it lean forward and she's off, without having to adjust her legs much.Anyway, there doesn't seem to be a consensus about whether it's actually bad for her to be doing that. I've read some articles that say it's awful, and some that say it's fine. Is there a consensus in the medical field about it? And if it is bad, how do I get her to stop? via /r/Parenting http://ift.tt/2mUszyl
