Steven,
"...Look at the words from another verse "Take the flounces fae yer goon, mak' a frockie for yer loon" -Loon here just means a male child... "
This line isn't as odd as it seems at first if the child is very young. It appears ir was quite common in pre mid-19th C Europe for a young boy to be kept in skirts until he was "breeched" (I suspect about that same age at a modern child comes out of nappies(daipers)/trainng pants).
