My dh didnt attend any of my nhs medical scans. Or mw appointments. They are medical appointments.
He did however book and attend the two private scans I had.
I struggle to see how the risk of infection to anyone is massively increased
Not everyone in the same household will get cv even if one person has it.
Your dp might already have it but not have symptoms and you not have it. Especially if you're not working, or wfh, and he is still working out of the home, or doing the shopping.
Having an extra person in there increases the risk to the mw. And to the next person in the room. Where will he sit, stand, what will he touch or hold on to? Much easier to see and predict where the patient is likely to be, touch, hold, than an extra body. What if the previous partner in the room had it?
a fight has been had over the years to say men should be equal partners is child rearing and here we are telling them they're not that important and they can wait in the car. Well, that’s a Stretch. Lazy fathers will be lazy fathers whether they attend a scan or not. They are absolutely not as important as the mother during a scan.
