The ones in the OP above are very soft-- my DD and I remarked on that at the time.  They wouldn't be bothersome to even most kids with sensory issues, I'd think.

Yes, something like that for early childhood education. In our case necessary due to developmental delay related to communication so if I could have had a Vegas edition in blinking neon lights projected in 3D the louder, the better. The transition to MedicAlert never manifested probably as he caught up developmentally he started to realize what he was wearing.

My daughter wears this.

We also have some normal bracelets that she can wear once she outgrows the cartoonish ones.

Yeah, I don't think my ds would have worn anything with a peanut on it.  LOL 
He wore the "sports" medic alert bracelets through 3 rd grade.  He had several a sports one, a bright orange one.
Later we switched to the metal ones.  I hate the clasp on them.  for awhile, he stopped wearing it because he had to remove it for sports which was an ordeal. 
I finally took the last one in for a different clasp and its better.  he does have to remove it for sports.   

While I think it'd definitely draw adults' attention, I can't even imagine wearing anything that looks like a nut on my body. Even if it has a cute face. Just looking at it makes me want to stop on it and/or set it on fire. It's like a creature from a horror movie. ::shudder::

ETA: Forgot my point, being to check with your kids before you buy something like this to make sure they're not going to have a negative visceral reaction.

They are a really good visual reminder for teachers, coaches, and other caregivers-- very bright and visible.   

I think they are great for younger kids!

my son now refuses to wear anything, even the £100 engraved watch I brought him.

he is very ,very stubborn.  he wore one from 2-12 yrs then and then removed it due to being allergic to the stainless steel /nickal etc. At 17 he is fast getting to a legal age to make this choice for himself, despite paramedics asking him to wear one!

Well, my DD is 14.  So take that into consideration... LOL.

She would perish of mortification, I'm pretty sure.

She has always worn a MedicAlert bracelet, however-- since she was 14 months old, in fact. 

I've started sending my daughter to school with these new bracelets I found.

She loves them and they seem to draw enough attention that the message is seen by her teacher and friends.

Has anyone else given their kids these allergy bracelets?
