We have explained multiple times that he is the person they need to talk to, and that I am not involved in these appointments. We’ve even had them put notes in the kids' records, but they still call me first. Do you have suggestions about how to overcome this bias (that doesn’t include me taking over the whole family calendar)?

My name is listed only as an emergency contact, but they still call me with all the reminders and schedule changes. If I don’t respond, they text me repeatedly.

My husband and I have four kids, so there are many appointments to make and keep. We both have full-time jobs, so we split up the responsibilities by category; I get the pediatrician visits, and he does orthodontist and dentist.
