Yes, we can definitely confirm that from our experience so far! We field tested the prototypes with all children in the team ages ranging from 10 months to 12 years. And we were amazed how good the reaction of the children was! With children from approx. 2 years you can discuss why it needs to be in the ear and that it helps you to help her/him.
They all forgot about it. Even my youngest daughter who was 10 months back then forgot about the degree° in her ear and did not try to rip it off. :-)
In case it somehow looses contact to your kid´s ear, you will be notified on your smartphone.
Note: The designs of our stretch goal might even make it more likely
that kids see a little „spirit animal“ in degree°.
