Welcome to YT! My Scooter has silky hair, my Maya has cotton hair that tangles very easily (a pain in the ars!), and my little baby Nikki (4 months old) looks like she has silky hair.......it's very fine....maybe even finer than Scooter's hair.......but maybe it's just 'cause she's a puppy. Be diligent and patient in the crate/potty training.......yorkies are, in my opinion, one of the most difficult breeds to potty train. Congratulations on your new baby!
