Big Brother Is Watching You
When a new baby arrives, the existing baby is automatically promoted to the role of big brother or big sister. As the letter board the kid is holding says: “They say it’s a promotion, but all I see is no pay rise and more responsibility.” It’s obviously a joke, but as they say: there’s a grain of truth in every joke. And in this case, it’s more than just a grain.
This pregnancy announcement is actually quite clever, because the parents are aware of the implications of having a new baby are on the existing kid. His role in the family will change, the relationships within the family will change, and everyone will need to adjust to this new bundle of joy.
