I am sure I would have done the same and ignored them and went on my way. But if I was passing by them I may have said something like "Aw, is it past his bedtime? I've been there with my kids and I've had to leave and come back later, at least there are 2 of you here so one could take him outside if you had to." And then smile warmly.
