The 34-year-old star, who has two-year-old son Camden and five-month-old daughter Brooklyn with her husband Nick Lachey, always feels proud of herself at the end of each day when her two kids are tucked up in bed and she thinks all mums deserve to be praised all the time for their multi-tasking skills.

She said: "I feel like the word mom and supermom should be synonymous. When you are a mom, you are a superhero. So while it is a juggle and it is chaotic, it's my chaos and at the end of the day, it's what makes my world go round."

Vanessa admits things in her house got more chaotic with the arrival of Brooklyn, but she wouldn't change anything about motherhood.

Speaking to PEOPLE, she said: "When I look back at one I'm like, what was I ever complaining about or what was I ever so stressed about? It's funny because everyone says you sleep when baby sleeps or you take a nap when baby takes a nap. That's true when you have one. When you have two, that is not true.

"It does feel like the day becomes more hectic, but in all the best ways and in every way that I wanted it to become because I always wanted to be a mother and I always wanted to be a wife and I've always wanted a family."

And Vanessa and Nick are very much enjoying Brooklyn being a baby because they still can't believe how quickly Camden has grown up.

She shared: "Instead of thinking about when (Brooklyn's) going to be there and what she's going to be like, we're just soaking up the babyness right now and the cooing and the swaddling for nap times with Brooklyn. I thought at two you were still wearing onesies that said 'Mama's big guy,' but Camden's like a little man."
