Sprogs are children.
Sprogs is a friendly and informal way to talk about kids.
Examples:
The park is full of sprogs playing on the swings.
She has three sprogs, two boys and a girl.
The sprogs are having fun at the birthday party.
The little sprogs were giggling and running around.
There were sprogs everywhere, laughing and shouting.
I love spending time with the sprogs at the daycare.
