I'll tell you two things I often do. You can try it on your baby.
Quaker cooks oatmeal, rice, coix seed, cornflakes, mushrooms, vegetables and lean meat into porridge, which contains basic nutrition. Sometimes it is enough to fry him a poached egg.
Or Quaker instant oatmeal soaked in milk directly, plus two pieces of walnut bread, meat floss and a few small tomatoes.
I think children are usually happy to give him Chinese food and western food like this. I hope your baby likes it too.
And oatmeal can also lower cholesterol, which is good for adults and children.
