I had to laugh just now when I read your comment about having to keep poking her head down in the bag repeatedly

  The visual of her popping her head out over and over as if to say, "Excuse me. ...why are you sticking me in here don't you know who I am," cracks me up!!  
I guess it's also bc I can relate, but mine is the opposite of your's.  In the bag I currently use, when I don't have the bag all the way open, I close the top piece... they know that means to get in their "house," and they never again attempt to poke their head up.  They are content as can be to lay in there and watch everything going on out the side of the bag. 
So, I thought the first outing in their stroller would be a breeze, and boy was I wrong!!


  I have had the stroller in my house for quite some time, and I just hadn't taken it out anywhere.  Well, I had my two dogs and my foster dog all going to the vet, and I have never had such chaos. They all kept popping their heads out of the stroller screen and trying to find a way to get out.  So, I have some work to do before my next stroller outing
