Paedotrophia

And I, for suckling, no fix'd hour prescribe;
This Nature teaches best the nursing tribe:
Let her our mistress be; and when, with cries
The hungry child demands his due supplies,
Forbear not you the wish'd relief to bring;
Nor then be loath your snowy breast to bare,
That he may suck, and streaming fragrance share.

Sainte-Marthe, Scevole de, Paedotrophia. London 1584, quoted in Ted Greiner's History of Breastfeeding.
