Here is a silly story I wrote for my daughter for when the time comes to transition her to her own room. I'm not ready for that just yet, but when I am I will read her this story.

Here is Charlie. Charlie is a big boy.
Here is Charlie's bed. But Charlie doesn't sleep in his bed. Only Margo, the cat, sleeps there.
Charlie likes to sleep with Mommy and Daddy.
Soon, Margo invited her friend, Fargo, to sleep in Charlie's bed too. Then Fargo invited her cousins Wargo and Dargo to sleep in Charlie's bed too. Then, Wargo invited Bargo and Dargo invited Pargo. And they all slept in Charlie's bed together. In fact, his bed was completely full of cats!
But Charlie didn't care, because Charlie slept with Mommy and Daddy.
One day, Charlie was given a Present. Charlie opened the box and inside was Bunny! Charlie and Bunny played all day together. When it was time for bed, Bunny wanted to sleep with Charlie. But, Bunny didn't want to sleep with Charlie's Mommy and Daddy.
Daddy's snoring hurts my long ears, Bunny said.
But where will we sleep then, Charlie asked? We can't sleep in my bed, it's full of cats!
Just then, Margo came in the room. Don't worry Charlie, she said. I will ask my friends to make room for you.
And so they did. The cat's all moved over until there was a tiny spot open in the middle. Charlie and Bunny hopped in. There was just enough room for them, and nobody else!
