How do I take my children to the doctor if the offices aren’t allowing siblings?

I’m in a Covid hotspot. All of the doctors here are not allowing visitors or siblings at appointments. My 3 year old needs a check up and my 1 year old needs to see the ENT for recurrent ear infections. Both offices will not let me bring their sibling. But I have no one to watch one of them while I take the other to their appointment. My husband works a very demanding job and is constantly having me cancel appointments because he can’t get off. We just moved here in April and do not have any friends or family around. The offices also aren’t doing virtual appointments.

Is anyone else in this boat? What are you doing?
