Also might I add to one of the comments about identifying as a parent.
I am a parent first and I do everything for my boys to make sure they're happy, healthy and provided with everything they need. However I don't identify as just a parent.. I do have interests, hobbies and time spent without my kids. The problem I have with saying your whole life is your kids is you lose yourself and once they're old enough to move out you're then lost in life with what to now do.
It's about balancing your kids with yourself and making sure your entire family is happy and healthy not just your kids. We go away several times a year without our kids for alone time to reset and our kids get to spend time with their grandparents. It's win win for all parties.
