Parents sometimes delay sending their children to kindergarten for a year if they have late birthdays, hoping it will give them an academic and social advantage over younger classmates. This practice of "redshirting" may help children who are not mature enough for the classroom demands. However, others argue it can pose challenges, like increased risk of bullying for being older than peers or not fitting in socially. Experts say parents should evaluate each child's readiness rather than act from their own fears alone.
