I'm asking Pod people because I'm sure you all have a lot of tricks! Emily started swim lessons and despite IV prep and a ton of Opsite, her Navigator fell off. I bought some Skin Tac and used that to insert the new one. What else can I do? She wears it on her arm. I'm thinking of something to wrap around her arm while she's in the pool. I would love to find something that would prevent water from getting to the transmitter, because it gets underneath the sensor plate and loosens the tape. Suggestions?
