Derick Dillard is getting a taste of fatherhood a little early.

Married to Jill Duggar Dillard, who has 18 siblings, Derick has been practicing his daddy skills on his wife's sisters.

In a sneak peek of the ninth season of TLC's "19 Kids and Counting" Derick and Jill host her sisters in a little sleepover, where Derick ends up fingernail painting -- something he had never done before -- considering he grew up with only one brother.
