Hello dear, as you are having twins of 5 yr age little difficult to manage but if with patience and understanding them you will try can give your best. What you do give them every type of food every 2 to 4 hourly including veggies, fruits, milk products, cereals and pulses. All food items should be pure and healthy preparations. Whenever elders are eating let them sit with their plates along with them on dining table to learn eating pattern
