Speaking through song lyrics

Phoebe once had this set of "Baby Yoda" dresses that she'd wear practically every day. Baby Yoda was her favourite animal for a time there. She adored him. 

But those dresses got too small for her, so I put them aside.

And then our Star Wars-loving neighbours up the street had a baby girl. So we gave them the Baby Yoda dresses. And now Phoebe is obsessed with the idea of giving this sweet baby everything. 

Whenever something gets too small for her she always asks if we can give it "to the little girl who lives down the stream."

I know she's talking about the neighbour's baby. 

But I think she's combining (1) "Baa, baa, black sheep" with (2) the concept of the baby living "down the street" with (3) "Row, row, row your boat." She says it in such a sing-song manner. 

I think she is purposely using "Baa, baa, black sheep" because that is mostly the tune that it sounds like. She fluently can substitute girl for boy in the song, but then she gets to the lane part—but who even knows what a lane is?!

She doesn't. 

But everyone keeps saying the baby lives "down the street." So I think she's attempting to substitute "street" for "lane," but then her knowledge of "down the stre..." from "Row, row, row" kicks in and she ends up with "little girl who lives down the stream" instead.

It's delightful.
