Until now Gavi wore a silicone medical id bracelet on his ankle, but it broke! I guess that will happen when he pulls on it. Any advice what kind to get? I don't think he cares as long as he can wear it on his wrist or ankle. I would prefer waterproof, but as long as he would wear it I don't care what it's made of! And if there is engraving, does it eventually wear off? I found one bracelet that's waterproof with a waterproof card to write the information on. If anyone has that one, do you like it? I just need to get one ASAP, I don't feel comfortable without him wearing one.
