My 16 months son did not wave bye yet. He is 10 kg. He did eye contact after 5 months after births. His neck was little cross but right now it is cleared. Now he can crawl stand and try to walk but keeps little more distance in his two legs. I have consulted physiotherapist according to him my son shows symptoms of mild low tone. Please tell me is it 100% curable. Will it affect his future life like studding, games. I want to know will he can did other activities like normal kid. Please help what treatment should I follow.
