Baby profile

Hello everyone Me and my wife are using a lot of the withing products: body cardio, sleep analyzer, bpm core, thermo. Each of us has a seperate user. I cannot remember why i did setup it like this, it was not about privacy but a limitation of one of the devices ( sleep analyzer i think) Now we have a baby on the way and i would like to continue using these devices for the little one. I struggle with setting up an account so both me and my wife can see the baby’s data and can use the thermo and body cardio ( in baby mode) to take measurements. When i add a test baby profile as suggested in my “Family” it is not visible in my wife’s app. Thanks in advance
