No, breastfeeding is definitely more popular among the general public in the UK rather than in the US. In the US, it seems to be more common in certain circles, but it's almost forbidden to share the news about breastfeeding within may other circles.
I like that Russia has women stay home for so long. It's another thing more accepted in the UK than the US too. But in both countries it is more and more common for a woman to get a short time at home and then put babies into child care situations. (Especially low-income women.) It's a sad thing, to be sure, and the society will pay in the long run. :(
