Oh how exciting! I know just how you feel! After a long wait, we will be picking up our baby this weekend! So a bit of good news...the time does go by quicker than you think!
I can't believe it's time for us already. I kept pretty occupied during that waiting time by buying stuff and reading lots of books. I bet I've read over 30 books on Yorkies, puppies, dog grooming, etc. It helped to keep me occupied too. And of course YT has been the best resource!!!
Here is our set up. We have a 'Potty Training Puppy Apartment.' We bought the octagonal play pen that you can order with it. Our play pen is a octagon too, but we did not have enough room to put all of the panels up. So we folded 2 of the panels shut and attached them to one of the other panels to save a bit of space. I'll try to show pix of that. Hope this helps some!
And Congratulations!
