It's an inevitable part of fatherhood – at some point, your children won't want to spend time with you. Rather than worry about the implications, you can embrace this milestone and support their independence.
Chances are, you went through the same stage when you were an adolescent, so you know that it's a harmless part of growing up. Don't take this shift personally – they're simply learning more about themselves. They're likely spending more time with their friends and less with their family, which also promotes growth. Though you shouldn't be overbearing, be aware of who your kids are friends with.
Trust is essential at this stage in their lives. After all, how can they gain independence if their parents are always hovering? Let your kids spend time with their friends and have faith that they'll make the right decisions.
Let them know that you're always there for them, regardless of what the problem may be. This way, they know they can approach you and seek advice. Leaving the door open to conversation will allow them to realize that you recognize and accept their independence.
