The intimate picture of Kerr taken by proud dad Orlando Bloom caused controversy when the Aussie supermodel posted it on her blog.
First photo: Miranda Kerr introduces her "darling little man"
Kerr has hit back at critics of the photo, saying she wants to promote breastfeeding and encourage other mums not to be ashamed of breastfeeding their baby in public.
"Honestly, I for one can say there are more breasts being shown on a daily basis around the world in swimwear and low-cut dresses and tops than there are from breast-feeding mums."
An advocate of organic products and natural healthcare, Kerr said: “I intend to breastfeed for as long as I can. My breast milk will give our little Flynn the nutrition he needs for his continued healthy development and to all mums out there I am sure you will make the right choice for you and your baby.”
