Child development experts say that jealousy in babies is a common reaction when a new brother or sister joins the family. Although babies cannot express jealousy with words, they often show it through behaviors such as increased crying, a stronger need for attention, or changes in sleep and feeding patterns.
According to psychologists, this happens because the older baby senses a shift in parental attention. The arrival of a new baby can create feelings of competition, even at a very young age.
Specialists advise parents to involve the older baby in caring for the newborn and to spend individual time with them, helping the child feel loved and secure. This approach supports the development of a positive relationship between siblings from the earliest stages of life.
