Two sisters have revealed how they breastfeed their nieces and nephews – and even friends' children.
Bunty Rowe and Kyle Aldridge went on ITV's This Morning to explain to presenters Philip Schofield and Holly Willoughby their belief that cross-feeding is natural and convenient and has even brought their children closer together.
The sisters, from Cam in Gloucestershire, who have seven kids between them, are both members of the pro-breastfeeding group Lactivist and have practised 'nipple sharing' for over four years.
Bunty, 26, who has two daughters Mabel, four, and Ede, two, said: "We enjoy breastfeeding. At the end of the day its all about choice. It's a convenience thing as well as emotionally comforting.
"I didn't want to give my children formula, that's just a choice I made, so it gave me great emotional comfort to know that if my sister was looking after my daughter she could feed her."
Her sister Kyle, 30, who has five children, explained: "There was never any big conversation about it it happened naturally when my sister went out one day and was nervous [about leaving her daughter] and I said if she cries shall I feed her?
"How often and how much has varied over time. It's all about meeting the needs of the children." The two women have been breastfeeding each others children for the past four years.
Kyle, a full-time mother to Jai, 13, Lottie, 11, Levi, seven, Judah, four, and Elijah, two , will sometimes breastfeed friends' children too.
She has started a wet nurse Facebook group in the UK to connect mothers who need breast milk due to an emergency or illness.
She said: "Breastfeeding is only a small part of your parenting ethos. Infant feeding is a bonding process but it's a small part of a big picture.
"It's natural. I see breastfeeding my baby and my sister's baby as part of motherhood - and sisterhood."
