The whole “not much of anything else” mellows out as they get older, and you can even share those interests with your kids. I loved the whole process of going to amusement parks with my daughter, watching her go from enjoying but also being terrified of the small ones, to getting used to those but doing the same for the medium ones, being nervous about going upside down, then seeing it wasn’t such a big deal and now loving the big ones as much as I do and we got to experience the most intense one I’ve ever ridden for the first time together.
