On The Lawrence Brothers & Their Mom, Donna, on Raising Kids in the Spotlight (2023) the Lawrences revealed that in real life Matthew Lawrence contracted the chicken pox around age 8, just after Andrew Lawrence was born. Andy subsequently caught them, which can be dangerous for infants as their immune system is still developing. Joey Lawrence also caught them, and being nearly 12 at the time he also had a bad case, as there are often complications with chicken pox in children over 10 and adults.
