Of course. Our oldest daughter values our opinion when it comes to our oldest grandson and comes to us, so as a family, we can have a game plan in regards to therapy, tutoring etc. as he has adhd and learning disabilities.
As for other subjects, all 3 of our daughters will come and vent to us about relationships, work, and friends. If they ask for our opinions, we offer them, but if not, we just sympathize with them.
