Wylie's fur was more medium length until about 10-12 months old. I will see if I can find a couple kitten pics of him to post.
I have heard that it's not uncommon for MC's to have shorter or less fur until they are older, and it has certainly been true with Wylie.

Also........they keep growing until about 3-4 years old (not 2 lbs. a month obviously , but some)
