This is a WWYD as I am fighting a VU urge to engage in passive aggressive behaviour at the school gates 
My DS randomly told me that I look like a teenager on the way too school (DS is 5 I am 26). He goes to an academy in a fairly liberal borough where most mothers are 35-45 (something I've never had a problem with). He also asked me if teenagers can become pregnant? At this point I ask him what inspired this question and he says a couple of children have asked him at school.
Does this sound like something a couple of five year olds would come up with by themselves? The use of the words teenage and pregnancy make me feel as if it was something they overheard their parents say. I don't know whether I am being sensitive due to background differences and feeling judged for not being the norm at the school gates.
