What would you do?

So I have a growth scan on Tuesday. Things fell through with the sitter for my 2 yr old. So thing is my husband will either have to stay home or I have to reschedule. I’m willing to reschedule but was really excited for the scan. My husband says I can keep the appointment. Idk what to do should I keep it or reschedule? We’ve had a private scan at 28&31 weeks and even for those he said he was happy to go but won’t be really excited until she is here. So it makes me feel like he really doesn’t mind I just don’t know.
