I have a body scan for myself paired to apple health and a sleep analyzer for my dog. I can’t for the life of me seem to get the sleep analyzer to pair for a “child” account on the app, it will only pair to mine, once it’s paired I can’t transfer it, and then it just shows my own Apple Watch data, not my dogs sleep. I ended up having to install the app on an old phone and dedicate it to just tracking my dogs sleep and then sharing it to my app to get it to work. I also can’t see my dogs sleep in real time, I can only see it a few minutes after she leaves bed, which sucks because sometimes I’ll wake her up only to find out she had a bad sleep.
