Girls good night everyone! I wanted to ask, we have such a problem or not even a problem, my daughter doesn't want to stand on her toes, she immediately sits down on her knees, she can't hold the support. A neurologist said that her legs are weak, go see an orthopedist, he sent us for an X-ray, in the end, thank God everything is fine ?? But she still can't hold the support, has anyone had this happen? And how did it get better then? Share it's very important ?
