I am at my wit's end trying to be a step parent to two children that have next to no discipline whatsoever. Any discipline or responsibility they are given is initiated by me following an argument with my partner.  Does anyone here feel frustrated  by being a stepmum and feeling that unless they proavtively put things in place themselves (ie chores, bedtime, giving meds on time, making sure kids brush their teeth, homework) these important things don't get done?
