How to Change a Diaper, 1612
The Cholmondeley Ladies, c. 1600-1610
“Dear Past, Do you have any advice for new parents?”
How the childe must be made cleane… The Nurse, or some other, must sit neare the fire, laying out her legges at length, having a soft pillow in her lap, the doors and windowes being close shut, and having something about her that may keepe the wind from the child… If hee bee very foule, shee may wash him with a little water and wine luke-warme, with a spunge or linnen cloth. The time of shifting him is commonly about seven a clocke in the morning, then againe at noone, and at seven a clocke at night: and it would not be amisse to change him againe about mid-night; which is not commonly done. But… after hee hath slept a good while do everytime shift him; lest he should foule and bepisse himself.
Jacques Guillemeau, Child-birth or, the Happy Deliverie of Women
