The ABA sells these cards to hand out to women. I bought some recently at the ABA Qld Conference. The cards I bought are much nicer than these ones in your link. They are worded much nicer and have the ABA logo etc on them with the website so Mum's know that support is available (if and when required).

I think if someone had given me one while I was out breastfeeding in public, I would have thought it was so nice of them. It wouldn't have creeped me out at all.... everyone is different though.

Heaven, if you're interested in seeing the ABA one's I have, let me know I can scan one for you and email it to you so you see what they are.
