Hi! My son is 14 months old. Alhamdulillah, he never get difficulties for eat. My wife just prepare regular meals like broccoli soup mix with potato and sliced meat. He likes fish so much. Chicken nuggets, fried potato,cereal, ice cream. Sometime also she served rice and "semi rice" with soya sauce. Nothing special. My suggestion: find out what he likes better than the other meal.

And also, let him to eat by him self, no matter how mess he would made. :)

Hopefully my answer will help!

Salaam.
