Why does the UK have the lowest breastfeeding rate in the world? According to Amy Brown of Swansea University, the answer may lie in social pressure to get babies quickly sleeping through the night and on a regular feeding schedule so new mums can get back to normal.

Brown spoke at the British Science Festival, suggesting an explanation for why just one in 200 British women are still nursing their babies after 12 months. First of all, the idea that women should get their babies on feeding schedules "is really incompatible for breastfeeding," she told The Guardian. Babies need to nurse a lot to get their moms' milk supplies up.
