I am ALL for breastfeeding and for working moms, but my issue would be that she brought her sick child to class, not that she nursed her while there.
As great as "collective childcare system" sounds, but bringing your child to work is not an alternative for most, so it is a legitimate argument that she was out of line.
That being said, the title of her class seems apropos!
What do you think?
