Karen Walrond is a mom of a 5-year-old daughter and says she isn't the mother she expected to be. Before having kids, Karen was a lawyer who flew all over the world for work. But when she became a parent in her mid-30s, everything changed. "When you're single and you don't have kids you think [when you're a mom] you're up for eight hours and you're on and on, but then you get to go to bed and you blissfully sleep and you don't have to worry about the kid anymore," she says. "That's just not the case. It's 24/7. I can't tell you how many times I've woken up in the middle of the night to make sure I heard breathing."
