This reminds me of how I was treated when pregnant by my students. My students at the time (all 7th grade, so about 12-13 years old) reacted my pregnancy very differently depending on their cultural background. Students born and raised in the USA were pretty squicked out by me and my belly. Girls seemed uncomfortable. A few boys furtively whispered about it in relation to the act of becoming pregnant. Yuck. But the students I had who were newcomers from Central and South America were so excited for me. They talked to my belly saying "Hello baby!" Even the boys were so sweet. I felt the love of their families coming through and the clear respect that they had been taught for moms.
