Hi ladies!

I posted a little bit back when we had the Jan 2011 DDC.
My daughter, Serafina, is almost 13 months. She just started physical therapy because she has low muscle tone in her legs; she doesn't crawl (she scoots with her legs almost in a split) and she doesn't pull to a standing position. She only cruises a little bit if you stand her at the coffee table.
I was just wondering if any of you had any experience with infant physical therapy?
