I could never understand why the producers would allow the baby of a sitcom show to go from newborn baby to a full aged 3 or 4 year old kid the next season that is kinda strange in my opinion, name as many shows as you can where the baby ages fast during the next season ???

Family Ties - Andrew (Andy)
Growing Pains - Chrissy

"Family Matters" with Richie!

Richard Crawford was a baby in the 1st Season (played by Joseph and Julius Wright), but on the 2nd Season...is 3 years old and played by Bryton McClure!

Nicky - The Fresh Prince of Bel-Air
Lilly - Step by Step

Nicky and Alex on "Full House"

Little Ricky--I Love Lucy.

Nicky from the fresh prince of bel air is a newborn baby in one season and comes back the next season looking like a 10 year old lol
