Anyone else have funny stories to share about children asking where babies come from?

On the bus a couple of days ago and my four year old asked the dreaded question! 😂

Where did my sister come from? Did she run into your tummy? Did you eat her! 😂 He's going to have such a shock when he finds out! I just know he'll be the kid who says at the most inappropriate time "you and daddy had sex!"

Thought I would start a light-headed thread with funny stories.
