When does Baby Bob return?

The Baby Bob character had previously been on television since February 2000, appearing in commercials for FreeInternet.com. While actual infants played Bob, the effect to make him look like he was talking was achieved through computer editing. The series centered on first-time parents Walter Spencer (Adam Arkin) and his wife Lizzy (Joely Fisher) and their six-month-old baby Bob (voiced by Ken Hudson Campbell)
