I didn't read the link, but to answer the question- yes, in MY experience it did impact on the division of labour. I am very strongly pro-breastfeeding and love breastfeeding my kids, in fact I feel blessed that I am the one the 'gets' to do it. However, when my DD was born, I feel the fact I was bf, and therefore responsible for feeding her, sort of led to the assumption that I was responsible for everything else. I don't see any point in my partner getting up in the middle of the night if I can feed so obviously that was my job, I would need to take her everywhere with me since I was feeding her, and it just kind of flowed from there. Of course, if I wanted my partner to do something child-related or domestic, I can ask him and *most* of the time he'll do it (eventually), but this in itself still implies that its *my* responsibility and that he's 'helping' me do *my* job, which in itself is an unequal division of labour.
So yeah, I think bf can often lead to men assuming that the woman is more responsible for the house and kids than he is. In traditionSl societies this would not be such a big problem as the men would have their own explicit responsibilities, however in the west often women get lumped with the house, kids AND paid work.
