Hide The Belly

My son really likes this show. It's cute.
I hadn't seen an episode in a while and I was watching the one where Leo got stuck in the elevator with the principal. I was like "Oh how cute! Leo's mom's pregnant!" Then I realized her character wasn't supposed to be.
A lot of shows do the "hide the belly" game, but she isn't good at blocking her belly at all. In that particular episode it was incredibly obvious. They gave her a big purse, but she wasn't very good at making sure it was in place.
Now we are watching the one where they are doing chores for money and she is less pregnant, but obviously pregnant and terrible at making sure it's blocked.
Just thought it was kind of funny and I was surprised no one had commented on it.
