It is fun to have fun! Vanessa Lachey (nee Minnillo) shared a sweet photo of her son Camden on Tuesday, Nov. 18, dressed up as Dr. Seuss' Cat in the Hat.

The 2-year-old tot wore the whimsical character's black and white suit, topped with the red and white striped top hat. Painted on her adorable son's face were tiny black whiskers and a little smudge on the nose. Beside the cute pic, Lachey included a quote from the beloved children's book: "Today you are You, that is truer than true. There is no one alive who is Youer than You."

The pregnant-again star, 34, added: "I love this quote. Be yourself, Trust yourself & Love yourself!!!"

In the December/January 2015 issue of American Baby, Lachey spoke about learning to trust and love herself in her role as a mother. "Once Camden was born, certain fears calmed down," she told the mag. "I no longer thought, 'Will I be able to do this?' My instincts really did kick in. We stumble and make mistakes, too, but that’s what learning is. That’s the beauty of it."

Her husband Nick Lachey, meanwhile, caught up with Us Weekly on Tuesday, Nov. 18, sharing his son's latest milestone. "We went to Disneyland a couple weeks ago for Camden’s first trip to Disneyland," the VH1 host told Us. "Which is a big deal: First kid's first trip to Disneyland is a special moment. That's the biggest, most recent milestone."

He added that the entire family is looking forward to welcoming a little sibling for Camden. "We have a baby on the way," Nick told Us. "It's one of those things where it’s always about family for us -- being with family, spending time with family -- we're expecting our second child somewhere around the holidays so it'll be a pins-and-needles kind of holiday for us, waiting for the little one. It's all about family spending time together."
