He sat like this for almost an hour - without toppling, just lifting his arms a bit and playing with his toy. I was actually sitting behind him incase he fell (Kyle took this picture and I am right outside of the frame). I cannot even put to words how happy I am that he is doing this! Yay - Go Nickolas!!!
Kim (our PT) always says that it isn't really anything that she is doing - but it is the work that we are doing at home. We are still working on trunk control, and sitting on the big bouncy yoga ball (latex free), and sitting in the corner chair. He is cognitively problem solving and interacting with toys and just growing up so much in the last couple of months!
Here is a picture I took of him last week (July 13) when he started sitting up (and not toppling over), wearing his blue pj's. Then compare it to the picture that I took of him yesterday (July 18). You can actually see that he is sitting up better and not sitting so far forward. - It's not just me, you can actually see where his arms are.
I have a video as well, but I'm not sure how it will load - but here you go.
