MY SON AGE 2YRS EIGHT MONTHS NOT ABLE TO TALK FREQUENTLY EXCEPT 2-10 WORDS AND ALSO NOT WALK SMOOTHLY WITHOUT SUPPORT . HE WALKS 4-5 MTR WITHOUT SUPPORT AND THEN FALLS. MY SON BODY IS VERY SOFT AND HE CAN ABLE TO STRETCH FULLY HIS BOTH LEGS. I SAW MY CHILD TO MANY DRS AND CHECK MANY TESTS LIKE FISH, THYROIDE TEST , MRI BRAIN TEST ETC AND IN ALL TESTS RESULTS SHOWS POSITIVE. ONE DR HAS SAYS THIS IS THE SYMPTOM OF HYPOTONIA. RECENTLY I SHOW MY CHILD TO ONE NEUROLOGIST AND HE SAYS THE VEINS FUNCTION IS NOT ADEQUATE AND HE SUGGESTS A DRUG CERECIEAN FOR 6 MONTHS. MY QUESTION IS WHAT IS THE ACTUAL PROBLEM OF MY CHILD.
