Often in therapy I'm working with a parent or parents who have adult children. Sometimes these children are in college or just out of high school and other families I work with have children who are in their late 20's or 30's. Parent come in for counseling at their wit's end, frustrated that their adult child isn't following their expectations. It's tough to know what boundaries to set with adult children and can be even tougher to actually implement boundaries with your adult kids. I've found in my counseling work with families that some parents are being taken advantage of, some are enabling unhealthy behavior, and some desperately want their kids to succeed and fear boundary setting will doom them to fail.  All parents I see deeply love their adult kids and want to see them do well in life. Setting boundaries with adult kids is important. It's important to let them make decisions on their own, even if they end up flat on their faces a time or two. Those can be learning experiences for everyone involved! Repeatedly bailing your adult kid out of a financial bind doesn't help them learn fiscal responsibility. Regularly allowing them to speak disrespectfully to you and disobey common courtesy while living in your home is not helping them with skills for success in the "real world". Boundaries look different with kids over 18 than they did with younger kids and the older they get the more different they can look. If navigating through setting boundaries with your adult children has been difficult, some family therapy can be really helpful. Often I just work with parents a while in counseling to create boundaries and implement them. Sometimes right from the start or later in the counseling process we involve the adult child. Reach out to a counselor if you're having difficulty with boundaries and your adult child.
