   the bigger picture in what you have said ( below) is that these women are
very conflicted about being mothers'parents... which they also only want to do
on Tuesday afternoons,  ....etc.

<< They would like to bf on Tuesday afternoons, and then not on Thursdays when
they want to do something else, and on Mondays if it's raining, but not on
weekends
 when their mum wants to look after the baby...and not at night, ever.  >>
