Mostly we have had reactions to ds8s inability to SIT STILL! Altough that has gotten considerably better in the last year or so. And people do tend to be amused by a medically accurate body parts vocab.
One lady stopped me in the grocery store to tell me my son must be gt, back when he was still a toddler, because he was singing about all the food. Now he is 8, he keeps a bit more to himself.
My dd2 is often the center stage character with her singing and dancing and general carrying on; people usually just say stuff like: she MUST keep you on your toes! She is under the weather this week, so I'm actually missing all the action!!
