With our family, it was thus:

Mommie buy me a big glass doll,
A big glass doll, a big glass doll;
Mommie buy me a big glass doll-
Do, Mommie, do.

What shall I buy it with? (3x)
Do, baby, do.

Sell Poppie's featherbed.

Where shall your Poppie sleep?

Sleep in the horse's barn.

Where shall the horsie sleep?

Tie him to the riverbank.

If you don't hush I'll give you a spank!
(Child interrupts, yells, "DO MOMMIE DO!" and runs. Mommie chases, and if she catches the "baby," gives her a play-spank.
