Carrie Underwood fans know that the singer is a doting mom to her two children, 5-year-old Isaiah and 23-month-old Jacob. But the youngest son of Underwood and her husband, Mike Fisher, can sometimes be a handful — and little Jake's got a nickname to match that character.
As any parent of two or more children knows, each kid has a unique set of challenges that goes along with their personality. In Carrie's life, that's borne out in her two boys — Isaiah has a knack for being the sweet, sensitive one. On the flipside, Jacob's turned out to be a little more rowdy.
