‘Growing Una and Cosmo’ depicts the breastfeeding pattern of our baby twins in the first month of their terrestrial life. It is composed of a series of twin circles on either side of a logarithmic spiral (also known as a growth spiral). The image was drawn from information about breastfeeding that I collected, in a series of notebooks since the babies’ birth. Although I had a sense of the ‘pattern’ of the breastfeeding, I wanted to make the pattern visible. The resulting image is an abstract representation of breastfeeding. Making the image involved patient care and attention, not so different to the kind required in mothering.
