as a rule, breastfeeding doesn't go on for as long in France (paediatricians recommend 2 months or so), but it's perfectly acceptable.
i hate the nestle baby feeding room with old adverts of chocolate milk for babies, but i've fed everywhere, including on POTC.
HOWEVER Tweedletum performed some kind of mime in Inventions in honour of me which was a bit OTT.
i've never been asked not to, and i've been quite a few times since ds2 was born!
