Good and nutrition. This is not eating!

Hello doc, My son is going to turn 1 year does April 4th but his eating habits is off a big tension for me. Even now he doesn't have rice and dal he really hates carrying food  it to his mouth especially rice. I was giving him a saucer size matter in the afternoon and night but these days he even not liking it he started dating now I am assuming this could be the sign of the thing of low appetite for what can I do in order to replace A deficiency of rice and dal as many advising that the party is not so good to give multiple times as it increases body heat. I try giving him all possible healthy food but he doesn't open his mouth at all he hardly have half piece of Toast and small babies watermelon and that's all for the entire day he is going climbing towards breast milk I am seriously worried about it is nutrition so is the party firing twice a day and what should I do if this is not eating
