Limiting fat before your child is two years old is not recommended. They need this fat to produce calories and maintain steady growth. This is why pediatricians recommend giving whole milk, which is rich in fat. Some baby's weight seems extreme - either too chunky or too thin. Your pediatrician can help you understand your baby's weight and recommend changes in diet, if he sees a problem.
Babies eat smaller servings than adults.
It will take time to work up to these servings, and sometimes a baby may be extremely picky about what foods he will eat during different stages of toddlerhood. This is common, and may be distressing to parents. You may need to get creative with your daily menu. While your baby won't be in danger if he eats only peanut butter and jelly sandwiches for a few days, it obviously doesn't give him all the nutrients he needs. Many babies love to dip finger foods into sauces or dressings.
