Lots of little kids have a favourite stuffed toy. Apparently some kids like to amass a crew of them.
My son always had his sheep (no longer stuffed), which has been renamed "Fwah" for some reason... but now he also has Doggie, Lion ("Ria") and Teddy. He has deemed them his bros, apparently, and they must travel together.
It's fun to go along with it, except for when he wants them all at the dinner table with us, or when we're trying to get going in the mornings. Or, you know, pretty much get anything done.
Anyone else's kid have a crew of buddies? Hmm, maybe it's a sign he's ready for a little brother...
