Is it normal for a 5th grade girl to have crush on an 8th boy?

It is not uncommon for children to develop crushes on older individuals, including those who are in middle school or high school. However, it is important to keep in mind that the emotional and social development of children varies greatly, and what may be considered appropriate for one child may not be for another. In general, it is advisable for parents and caregivers to monitor and provide guidance for any relationships that develop between children of different ages to ensure that they remain safe and healthy.
