O - I have never once discussed bedtime routines or haircuts for my D's with my EW. Who was normally responsible for his haircuts? IMO the only thing worthy of reaching out to your W for in that conversation was the behavioral problems at daycare. Is your S's school aware of your sitch? Not the details but that you and your W are separated? Just so they are aware and keep their eyes open to any changes in him at school.
I agree with what the other have said.
I would only contact her going forward if it is absolutely critical S conversation or financial. Maybe in the future more dialogue can take place but not right now. The emotions are too raw.
