As a single mom, I'm juggling a lot and working long hours. Yes, it costs them a little, but what my children get in return is a mother who is energized and content.
Being a single mother was the right thing for me. But I have a tremendous amount of help from my friends. They're in love with my kids, and my kids are in love with them.
Is it harder having kids and working? It definitely is, but the payoff is you get to go home to your kids, and it all balances out. And I know I'm a better mother when I'm engaged in something outside of the house.
