Young children need to eat enough nutrients every day to grow healthy, strong and intelligent. At about 9 months old, the baby is growing rapidly and needs more energy and nutrients than at any other time in life. Therefore, parents need to understand the nutritional needs of 9-month-old children to supplement appropriately.

Eating less, eating poorly or losing appetite are signs of anorexia. A 9-month-old baby eating less occurs when the baby does not eat enough food to meet his or her needs for at least a month and shows signs of slow growth. In addition, a 9-month-old baby who is a picky eater also never shows hunger, demands food or shows no interest in food.
