Children Safety ID Wristband Reusable Identification Bracelets Waterproof ID Band Safety Wristband for Boys and Girls, 6 Pack

Good idea. When my daughter was a toddler, when we would go on trips, I would put a disposable Tyvek ID bracelet on her with her wrist with my name and contact info in case of any emergency. I used something similar to this, but not the same brand. https://www.amazon.com/Children-Wristband-Identification-Bracelets-Waterproof/dp/B004TADO3W I see that now they sell reusable ID bracelets made out of more durable materials. I would also point out some tall structure and tell her that if we get separated, to meet me there.
