I loved Maurenne's descriptions of bf in kindergarten. I speak Hebrew with my kids, and in Hebrew the word for mammals is _yonkim_, literally sucklers, the same exact word we use for bf babies. (same as mammals, but no latin to obscure the issue, I guess). Anyway since I was more likely to talk to Avital about zoology than anyone else in her life, for a long time she referred to mammals as "nursing animals," and now, at age 4.5, her favorite game is still "I'm a baby [pig, dolphin, kitten, etc] coming to nurse from the mamma [pig, dolphin, cat, etc]." You bet all her friends know what a mammal is... Elisheva Urbas NYC
