Is this unprofessional or just me?

I’ll start by saying I’m also on the spectrum and don’t do well with change in schedule. My daughter’s OT had to miss a few weeks of therapy for personal reasons. Her company has a policy that we have to do make up visits. I’m fine with doing them as long as they’re scheduled. Since they’re in home I need time to clean up after my toddler for a visit. And time to mentally prepare. For the past week she’s texted me multiple times asking if she can do a visit within the next hour or so. Her company has a policy (not positive if I remember correctly) that they need to give us at least a 24 hour notice. So This caught me off guard. Our old OT never used to do this. My toddler already doesn’t like this OT. And this might be the thing that pushes me over the edge to switch.
