Google Voice Family Number?
I had a slightly unhinged phone number idea earlier. I would set up a "reach mom & dad" google voice number that would ring both of our phones (I think this is technically feasible, but not certain yet). This way if daycare or a doctor's office is trying to get hold of us, they call one number and one of us would likely answer.
The longer motivation: We have 2 under 2 in 2 different daycares and my one son has some health stuff, so the phone calls to schedule appointments is unending. For some reason, everyone always calls the least ideal phone number (my office phone when I'm driving back from another appointment, etc.)
Has anyone done anything like this? Is it helpful or just even more maddening? I think we're nearing the end of the constant scheduling of appointments, but right now I get so frustrated whenever I miss an appointment call.
