Hello dear moms! Could you please tell me, my daughter is 8 months old…

Hello dear moms! Could you please tell me, my daughter is 8 months old and turned 3 days ago. She has been crawling like a baby soldier for a month now. She can't sit or stand on her knees. But she is active and curious. I am very worried about this. A neurologist diagnosed hypotonia of muscles. I have enrolled her in swimming lessons and exercises according to the specialist's recommendations for motor development. Has this happened to you before?
