I don't know about you guys...but DH and I very firmly tell people, "do not touch my child. You are committing a misdemeanor and it is called battery. do not touch without asking. we find it very offensive." (we say this as they reach in for a touch)
you never know what someone was just doing before they touch your DC...pooping, not washing hands, smoking, doing drugs, having sex, touching poison, touching something that you or DC might be allergic to...
I know we may seem harsh but I have DS's safety at the forefront of my mind.
oh yeah, and I wear DS constantly in the wrap
