We are still working on the crawling, but Ruby is progressing more and more with that each day on her own. The next stage in PT is getting her to pull herself up from the ground. Correctly. She's a pro at pulling up from a small seat, but from the ground is different. She basically tries to do a pull up and doesn't use her leg strength if left to her own devices. I've been working on helping her do it correctly for a little while though, and after just one session with her therapist, she's doing it almost exclusively successfully AND correctly.
*Note: I do not always use food as motivation, but after she's worked on a skill for a long time and I finally remember to pull out the camera, Ruby needs a little coaxing to still be interested.
