I use my phone for work. My child sees me use my phone 8 hours a day. Of course she wants to use the thing she sees me use all the time. She loves taking pictures on our hikes and looking through the photo albums. This is completely normal and supervised.
What’s weird is all the assumptions that I would let my kid have free rein on a smartphone, and assumptions as to how my child really enjoying using my phone is somehow a bad thing. We live in a not great part of town and having gps tracking, only mom/dad/grandparents as contacts, and other safety features makes my old-gen smartphone a good lifeline.
Ya’ll are missing the forest for the trees with your assumptions.
