Hi,
My ds is turning 3 in April and he doesnot construct sentences. He communicates to us by mentioning one word i.e Daddy, Mummy, Open, bathe, switch on/off, he can count up to 10 and he can say A-D, he can sing some songs, he recognises people in pictures and every thing else is normal.
He is however very active - when we go out to of the house, he can never sit down - he walks/runs without even watching where he is going and he never gets tired - he has a habit of running along side walls, vehicles, windows (anything in a straight line and at his eye level) - he runs side ways with his eyes fixed on the object - one level and he turns the eyes as he runs along - we find this behaviour not normal - please advise.
