OP - don't you have to start school before the kids go back on the 8th? All our teachers start 2 weeks before the students as they have professional development trainings, various meetings, and they have to get their classrooms ready for the new students?
If I tried to make not just one, but three well visit appointments less than a month from the start of school, the nurses would laugh at me.
Not sure why you are sitting by the phone. Even if they leave a message, you will know the computers are now up and you can call and confirm the appointments they suggested.
Do you have a voicemail feature that transcribes the message and sends you an e-mail? We have this with Comcast/Xfinity. So, even if somebody would call my house phone, I would get the e-mail right away on my cell phone and I could call the office back. In today's world of technology, there is no reason to have to sit around and wait for a phone call.
