So I'm newish.

I've been with my partner (not husband) for 3 years.  I have sole physical and legal custody of my kids.  His kids stay with us every other weekend.

I'm losing patience with the nine year old.  In the past months, she's wet the bed twice and not said anything, leaving it to soak in for 24 hours.  The first time we discovered it, princess told daddy someone else wet the bed.  My partner told her accidents happen, BUT it's not okay to lie.  It's not okay to let it soak in all day.
