My son is almost 18 months old, hes my first and has always been a smaller boy. He has always been between 5 and 10 percentile since birth for weight.

But he has been refusing to eat lately. He maybe takes 2 bites of his food and then says all done. I'm feeling so sad and discouraged about it. I dont want him to develop any deficiencies in his diet but I can't force him to eat. Please any suggestions would be fantastic.

This is my tiny boy. He weighs 21. 3 pounds
