Yeah, sounds like a compromise is in order!
Might have to be a little of give and take.... maybe if you could give her something (time, a celebratory ice cream, something like that) and make an agreement that you get to pack after that. Can't think of anything else sorry!

We have the same issue when I am trying to study. Littles keep popping out everywhere and stealing all my time. Still working on the whole compromose thing here too, eh.

Good luck. I hope you work out a way to get your packing done!
