I normally don't recommend products on the Bump and I am not often on here as my DS and DD are celiac but then I am as well.
I am now running into issues as my DS is 4 and is going on playdates and although he knows what he is not allowed to eat, other parents have trouble understanding him.
They had the bracelets on kidsteals a while back and I bought two and they have worked so well that I thought that they might work for someone else to.
Re: Very hand item....
They sold these at a kids gym i took DS to and have contacted them multiple times to ask if they will make them where you can just add links (since DS has multiple allergies) and they said yes but haven't yet (at least i don't think so).. but i ended up buying a different one.
they definitely are super cute in real life
I know that they have the necklaces that can have multiple tags as fI bought them for my friends DD but she is older.
I wish they had that for the bracelets too.
