Do you think she sits well for being 6 months?

After awhile a few minutes she falls over, but do you think she sits well for six months? The reason why I’m asking is because the doctor recommended to take her to physical therapy because while she was examining her she didn’t support herself with her hands while trying to sit and sort of just fell over. I really think it’s kind of bs that she suggested physical therapy so I’m thinking I’m not going to go, but I wanted to see what everyone else thought.
