Classical Usage: Rochester uses this chiefly Scottish term to refer to Adèle when Jane asks if she may accompany them on their first trip into town as a couple. “Do you really wish the bairn to go? Will it annoy you is she is left behind?” Jane gets her way.
Classically Mad Usuage: We all have bairns. Also, most of our bairns are old enough to figure out when we are trying to speak in code about them to our husbands. Maybe referring to them as a bairn will help make the code a little less breakable. Especially if we spell it. Backwards.
