When I crate trained my Chihuahua I was lucky. She kinda took to it, BUT I did know to place my t-shirt in there along with a toy. I'm gonna suggest going to the thrift store and stocking up on baby towels, baby blankets and t-shirts for your crate because the baby will have plenty of accidents. That means plenty of doggy laundry. LOL You don't want to have to use all of your favorite tees for the baby. I have bought all of my baby's blankets & towels from the thrift store. Both of the girls have receiving blankets and the baby towels with the little hood. It's cheap, and if they get torn, damaged, or stained, it's not a big deal.
Remember, (s)he is just a baby and crying & whining comes with the territory. They;ll be fine. Just give plenty of hugs & kisses when they come out of the crate.
