I've also had 2 past families call me a night because their child has a bruise they've never seen before. Child was under 2 and not long walking..ya ok...I was really offended at first and then I thought about it, and I said to myself, self I'm not going to let this stress me out I may be the same if it was my child (not) anyhow, so I said to the parent, call me anytime if your wondering and if I know where it comes from I'll tell you, if not oh well. I wasn't sure what would happen after and there were some scratches here and there but they were good about it. Because I decided they were not going to put me down, so I said very casually, no problem kind of voice, Call me anytime about anything, I did assure them that I would always try and tell them first even if they had a little fall. It worked great for me, this is a really stressing phone call to get at night then I worry and worry. Not after this . I really felt relief. But if it continued I would have told them to go elsewhere.
