My daughter didn't have baby milk either. Breast milk all the way. But... different mums, different choices.
BradfordLass72, exactly. Market forces. I'm sure Cow & Gate, Aptimil and SMA are more than capable of meeting demand. Shops just need to allow for constant restocking. They too make a profit after all. Hire shelf stockers to work during store opening times, not just for after closing.
I guess poorer Chinese, e.g. average mums, breast feed. Certainly I've seen mums in Shanghai breast feeding on the metro there. No one bats an eye. Must therefore be standard.
