Thanks ladies.

I did mention it to mom that we don't spank our kids (and certainly not the day home kids) so it wouldn't have been something they heard from me. So far it's just my 2 and her and I've never heard the verbal of my two mention it. I'm certain it came from somewhere else (their previous day home, family or friends). I just hate being doubted. I'm going to have to stay on guard for any additional comments like this. Like you said, don't want to work under a microscope.
