The pediatrician diagnosed the child with hypertonia. We've been doing light gymnastics at home for a month now. I know that infant swimming and massages are very beneficial. But the doctor has only recommended gymnastics so far, everything else is just a month in three. I don't want to waste time, I want to treat everything on time. What did you do if your child was diagnosed with this condition a month ago? Were you limited to gymnastics or did you do anything else? Thank you for your answer.
