In the dark, also, the general character of her breathing sounds was interpreted with great accuracy in terms of her varied needs, her comfort or discomfort, etc.

The same kind of suggestion from the respiration sounds now troubles me whenever one of the children is sleeping within hearing distance.[13] [Footnote 13: This is an unpleasant result which is confirmed by professional infants' nurses.

Mrs.James Murray, an infants' nurse in Toronto, informs me that she finds it impossible to sleep when she has no infant in hearing distance, and for that reason she never asks for a vacation.
Her normal sleep has evidently come to depend upon continuous soporific suggestions from a child.
