Actually yeah, completely serious. It makes me sick. A low socioeconomic area, full of immigrants, the poor, uneducated etc...and a poster advertising how much better formula is for your new baby. Wrongtown all the way. I was proud as punch when DH told me what he did. Not to mention it's just plain illegal. There are rules in place for a reason, they're not made willy nilly.
I have to say, that comes across a little bit 'ist' - what 'ist' I am not sure, but just because people come from poor or immigrant or 'uneducated' backgrounds does not make them idiotic......I've seen alot of very well educated, rich and australians who make equally poor life choices.
