Reply to Tracking devices for Children

I just ordered a tracking watch. It hasn’t arrived yet. I’m worried my daughter will accidentally set off the alarm. I’ve also debated giving her my old iPhone just for games instead of a tablet. Then I can add find my kid and track her that way. Also it listens to the surroundings and I could hear what’s going on around her. I use this app with my mom and gma. Neither answer the phone and our family was worried where they were and if they were okay. It’s hard with younger kids.
