If i pay for premium, why does my husband's linked app still remain as the free version.. why should we pay for premiun twice to take care of the SAME child ???

Also, if i start the sleep timer on my app, it doesn't register on his app until i stop it on mine.. if i click and it says the baby has been sleeping for 10 mins so far, he should be able to open his app and see the baby has been sleeping 10 mins with the timer on his app.showing the same time as mine!!

So that way if I'm at work, i can pull up my app and see in real time whatever my husband is doing at home. Please fix this
