Today my little one was sitting on my lap after soccer practice and somehow the transmitter popped off of her arm. This is never happened to us before and it was a bit scary if it happened when I didn't notice. The tape is still on fine and I hate to pull it all off and redo it but I can't seem to pop the transmitter back on without the little piece of plastic that usually helps click into place. Or at least she starts complaining that it hurts too much so I can't push very hard. Are there any tricks to doing this or am I stuck peeling off and starting over.
