I'm sure I'm an exception because I only train in underwear, each to there own, but what gets me is that the parents have the ordasity to not inform you of their plans. It's not about needing permission as obviously they are the parents but this is supposed to be a collaborative relationship and this is a clear indicator of how little respect they have for you and your role.honestly, I would have said it's not happening and put him in diapers. My house, my rules. If it meant that much to them, they should have had a conversation at the very least with you prior to starting and got on the same page. No verbalizing of their toileting needs just reinforces that the child isn't ready so it doesn't need to be difficult, it just needs to be a no.
