LITTLE STYLE :: Who Makes One-Piece Cotton Sleepwear Above Size 2?

Does anyone know of a brand which makes this style of romper — cotton, one-piece, footless — in higher sizes? Most labels stop at a size 2. Even Hanna Andersson only makes one-piece sleepwear through size 3, and then switches to 2-piece.

There HAS to be someone who makes sleep-appropriate cotton jumpsuits (even short-sleeved/short-pants ones) for kids past the baby stage! Help me out?

UPDATE: The wonderfully helpful POP Street Kidz curator and readers have found several options! They are all listed here on the POP Street Kidz Facebook page.
