Many parents of children with autism may not have the same success as Jenny and Holly, but these Hollywood moms want them to come away with one thing—hope. "I want to say [to parents], you're not alone. There's a lot of hope," Holly says. "It's a new day in the world of autism, and we're fighting."

Holly says the CDC's statement about vaccinations has given her hope that parents and medical professionals can lay down their arms and open the lines of communication. "I would just say to the pediatricians, listen to [mothers] sometimes and give us a little bit more respect," Holly says. "Our gut is really dead on."

Jenny urges moms in her situation not to feel guilty about their child's diagnosis and to trust their instincts.

"You're mother warriors is what you are," Oprah says.
