Stuck on a scene

I am stuck on a scene that I am having a hard time getting to the end of. There is a lot of action and I am worried that I am over explaining it. I think my problem is that this is not a scene I originally planned on putting in the book. But, I need it to get from the scene before it to the one after it. I don't think I have really been able to visualize it yet. Hopefully after I get through this scene I will be able to move more quickly.

On the mother front, I'm trying to figure out whether I should be concerned that my 2 1/2 year old's new favorite work is underpants. I figure it could be worse so I should just wait until she gets tired of it and moves on to something else.
