Ok, it's late, so I just skimmed the info in the link. But did that say that we can BF in the pools here in Canada? To be honest, that suprised me. I, of course, would never want to be discriminated against while breastfeeding in any place. But if someone asked me not to nurse my child while swimming, it wouldn't even phase me. I'd just climb out and nurse him next to the pool. I guess I'm so used to "No food in the Pool" rules, that I probably wouldn't even think to nurse him there. Breastmilk is, after all, a type of food. It'd suprise me to see someone bottle feeding their child while taking a swim. Or munching on a sandwich while taking a swim. And while I agree that a little leaked breastmilk in the pool is no big deal (there are far worse things entering public pools), I also think that climbing out and sitting on the edge of the pool, or on a pool-side lounger, is also no big deal. That's what I've always done, anyway.
Of course, if someone asked me to get out and take it to the change-room, that'd certainly rub me the wrong way. I can totally understand why the OP would be upset about that.
