That's great that she's interested in sharing with you As, that's fantastic. Is there a way to create an opening when you two switch for the kids, but one where they can't interject and take the focus away?
It sounds like the best thing to do would be to grab lunch or coffee with the specific intent of listening to her talk about her work, but that may be too bold a move at this point and come off as pursuit. You're kind of in a bind that way.
Next time you see her, I'd let her know that you're really interested in it and the last time when she started talking about it the kids got in the mix. Let her then set the stage for the how/where/when that she's comfortable with.
"hey I'd love to hear more about your research, last time we got cut off by the offspring...." (door is now open for her to let you know what way she wants to share)
Then it sounds like you get to sit there and enjoy a delicious cup of STFU and let her talk. And then maybe a second cup...
Hopefully the vets will chime in on this one. I still say it's a good sign.
