I think that’s the best plan. Just be kind.
Maybe tell her that you need her help, but you also need to make sure she’s healthy enough to help you so you don’t have to worry for no reason.
If you’re sure you can tell when she’s having symptoms, I think you should be OK - just remember, even on their regular dosages, some people have breakthrough symptoms. I am guessing you know that, so you’re probably already looking for that anyway.
It sounds like you guys are doing really well all things considered.
