My 9month old with 2 centre teeth below & 2 lateral above erupting just now is refusing to eat / takes very minimal interest in solids food , like breads , well mashed rice with veggie.

At the same time he is interested porridge , nicely ground cooked rice & all puréed food .

I am worried at where this will go to . How to make him interested in proper solid food ? Is it too late or too soon or just about time that he moves to proper solid food ?
