Mrs. Bloomfield is the mother of the first set of children that Agnes takes care of. This woman will not allow Agnes to punish the children if they act badly because she does not seem to believe her children act badly. She describes these children to Agnes in terms that Agnes does not believe fit the children. Even when Mrs. Bloomfield sees the children misbehaving, Agnes thinks that Mrs. Bloomfield believes these actions are somehow Agnes' fault. It is after Agnes kills a nest of baby birds that Tom is about to torture that Agnes first stands up to Mrs. Bloomfield for her actions. It is also after this incident that the Bloomfields seem to be looking for additional reasons to let Agnes go.
