When an individual changes his/her personality to the extreme after having a child, causing this person to completely change his/her group of friends. This can be due to drastic lifestyle changes such as no longer going to clubs, or drastic changes in opinion.

Because of the changes attributed to "parent crossover," many people who get married/have kids before age 25 end up breaking up friendships/ties with those who haven't had kids yet.

In many cases, the person was the most promiscuous and drank the most of all of their friends, but completely do a 180 after having the child, next proceeding to criticize their friends who drink/go out, etc.

In some cases the person undergoes this change for the best interest of the child. In other cases, they are simply jealous that all their friends get to go out when they can't.
