First, congrats on your soon-to-be-child. To chime in as a parent, I never have needed this feature to date. The only times our son was alone in a room was when he was sleeping and we were close enough to hear if he woke up. I'm sure YMMV so hopefully you have a good use for it but we were definitely too protective to leave him somewhere that we'd want to "drop in." As for my parents, they can message me anytime to get video chat if they want. I can't imagine them wanting to watch my child without me there but who knows.

In terms of using it when your child is older, I'm not sure you'll be using the same device 3+ years from now.
