We have been working and working to get Levi to do this, and he made a breakthrough during his physical therapy session this morning!
The low muscle tone and lax hip joints that come along with Down syndrome make crawling one of the most difficult tasks for our kids to master. Many never truly crawl on all fours but get around with an army-crawl. Just getting Levi to hold this position without support is a BIG DEAL! Hooray! I think the yoga mat was helpful. It gave him a little extra grip that he can't get on the carpet.
