Hi Raechel! Welcome to Yorkie Talk.
Congratulations on the new addition to your family. I love the name you have chosen.
You have a great list of essential supplies. Make sure the brush doesn't have balls on the end of the "bristles." A little mustache and leg comb is very handy too. I like to use conditioner after shampooing. It closes the cuticle on the hair shaft to give a smoother feel and appearance.
Depending on your home, you may need a baby gate or two. We use them to keep the boys from the doors because one of them will run outside when grandpa opens the door.
Enjoy and be sure to share pictures here!
