Older brothers and sisters learn quickly that babies only drink breast milk or formula. Once you start feeding your baby jarred foods at six months of age, an older sibling may think it is okay to share his food with the baby. Therefore, make sure to tell your older child that even though the baby is now eating from a spoon, he is still too little to eat “big-boy” food. If your older child is anxious to feed the baby, you can supervise spoon-feeding once the baby has demonstrated that he is a competent eater. Make sure that you stay alert for sharing even though you have warned your older child to keep his “macaroni and cheese” to himself.
