My son will be one on Friday and he doesn’t stand independently and he isn’t walking yet. He can walk with his walker and he can walk on the edge of the couch / while holding something. But he doesn’t want to walk by himself and he doesn’t stand yet alone. I just found out that “ w sitting” is bad. My son would sit w sitting while he plays and I just started to correct it. I didn’t know it was a thing and it wasn’t good to sit that way. I’m nervous that has something to do with not walking yet?

Any advice?
