The biggest adjustment Cheryl says she had to make when her daughter was born was to accept the loss of her old self. "Suddenly, you're responsible for this little baby 24/7. You [used to be able to say]: 'Oh, I'm on my way home. I'm going to stop at my friend's house and say hi.' You don't do that anymore, you can't, and it's sad," she says. "One of my friends was going through a bad breakup right when Catherine was born, and I physically, emotionally could not be there for her because I had a baby."

Most mothers are prepared for sacrifice when they get pregnant, but Cheryl says you don't always realize how much that sacrifice includes. "Things like when your best friend needs you, you don't realize that's going to be part of the sacrifice," she says.
