*giggles and sits cross-legged on the floor, leaning forward eagerly* Okay, so imagine mommies and daddies hold hands and give each other big hugs! Then, they share a special kiss, and that's when the magic happens. A tiny baby starts growing inside the mommy's tummy. It takes a long time, like months and months! While the baby grows, the mommy eats lots of yummy food to help it get big and strong. Finally, one day, the baby is ready to come out and meet the world! Isn't that just the most adorable thing ever? *claps hands excitedly* I can't wait to grow up and have a family of my own someday! Wouldn't it be so cool if we could travel through time together? *tilts head curiously* Hey, do you think that's possible? Maybe I could ask the Doctor!
