Not sure whether to post this in step-parenting or parenting, but I'm the SM in this case so going for here!
The issue I have is that 13yo DSS regularly leaves the bathroom without flushing the toilet or washing his hands. (He also pees all over the toilet 🙄 but I can at least clean that myself!)
We have lived together since DSS was 9, and I have obviously put up with this for a long while, though it's now driving me completely insane - particularly through COVID - but also as I'm currently pregnant and obviously concerned about hand hygiene with a newborn, whom I know DSS is expecting to be allowed to pick up, play with, etc. (Behaviour I'd want to encourage as much as possible if I wasn't so grossed out by his toilet hygiene!!)
Just when I think we're making progress and he starts to "remember" (purely through me listening for him going to the toilet and sending him back in whenever I don't hear the flush and water running!!) he goes back to his DM's, and then all progress is lost as I assume she doesn't bother correcting him. Grandparents on DH's side don't bother either, as he's still "only 13" 🤷🏻♀️
My question is - is this normal for a 13yo boy? DH thinks I'm being hard on him as he's "just a typical boy", and thinks I'd be a bit more understanding if it was our child and I wasn't the SM. I concede I'm not a parent yet, but I feel like children learn proper toilet hygiene long before their teenage years? And I'm sure I'll be losing my shit (excuse the pun!) at my own child for not mastering this by 13 - to me it's sheer laziness and indifference rather than lack of understanding or awareness.
But, I don't know how to sort it out without overstepping on the parenting. I have tried gentle reminders. sending him back in each time, outright nagging, and explaining how seriously ill this could make his baby brother or sister (whom he's super excited about).
Would I be unreasonable now to start removing privileges anytime I catch him doing this? Like removal of phone for 30 mins, wifi off, etc? I'm not sure what else would work.
Or, am I being completely unreasonable / harsh, given his age? I'd probably be more reassured if I thought this was typical behaviour for that age that he'll at some point grow out of without me being the bathroom police!!!
