I have to say Jessey that your comment sounded very harsh to me.
Breastfeeding is more than nutrition. A breastfed child is that. Breastfed. I dont really understand the necessity of overnights at the detriment to the breastfeeding bond of mother and child.

I think it's important to remember there are feelings & emotions that go along with breastfeeding. For both mother and child.

However, remembering also that divorce is difficult. The best interests of a child I would think is to have his or her life remain as "usual" as possible. Abruptly ceasing breastfeeding or indeed trying to coax an under 2 to have a bottle rather than a breastfeed would be difficult for the child. I think it would be difficult to argue that ceasing breastfeeding or beginning to bottle feed to facilitate an overnight visit by another parent may not be in the best interests of a child. Not to mention the Mama.
