There was a special reason, besides the general interference with discipline, for which the bishops objected to children in nunneries. It seems very often to have been the custom for the nuns to take, as it were, private pupils, each child having its own particular mistress. This custom grew as the practice of keeping separate households grew. Thus at Catesby the Prioress complained to Alnwick that sister Agnes Allesley had "six or seven young folk of both sexes, that do lie in the dorter"; at St Michael's Stamford, he found that the Prioress had seven or eight children, at Gracedieu the cellaress had a little boy and at Elstow, where there were five households of nuns, it was said that "certain nuns" brought children into the quire. In fact, the nuns would appear to have kept for their own personal use the money paid to them for the board of their private pupils. This was a sin against the monastic rule of personal poverty and the bishops took special measures against such manifestations of _proprietas_. William of Wykeham in 1387 forbids the nuns of Romsey to make wills and to have private rooms or private pupils, giving this specific reason, and at St Helen's Bishopsgate in 1439 Dean Kentwode enjoined "that no nonne have ne receyve noo schuldrin wyth hem ... but yf that the profite of the comonys turne to the vayle of the same howse." Similarly the number of children who might be taken by a single nun was sometimes limited; Gynewell wrote to Godstow in 1358 "that no lady of the said house is to have children, save only two or three females sojourning with them" and at Fairwell in 1367 no nun might keep with her for education more than one child.
