Historical information
Nipple shields will help some babies attach to the breasts, that are otherwise unable to. They are used occasionally with women who have flat or inverted nipples and their baby is unable to attach to the breast. Shields are made of a fine, silicone material that sits over the areola and nipple.

The business card [118.4] belonged to W Henderson, who was most likely a sales representative of Surgical Manufacturing C, 191 Lygon Street, Carlton. The card was inserted into the box with the nipple shields, suggesting that the product may have been distributed by Surgical Manufacturing.
