I got word back from Michelle, who posted above. The poem she's looking for is this one (taken from post above):

My late mother used to recite a poem which we called 'At the Churning' which would be Ulster-Scots/Scots-Irish derived. The first verse was
I was at the churnin' and hadn't room tae turn in
Wae all the childer roun' me on the floor
Away out the whole o' ye, the divil take the lot o' ye
An' like a flock o' chickens I chased them to the door.

The poem ended with the littlest child 'wee Johnny' creeping back in and when asked what he wanted the response was '"Just a wee sup o' buttermilk" said he'

Anybody have the complete words of this poem?
