Is it their other parent? Who is 100% all the time their parent even when it is not their contact time.
Or is it me? Who married their dad?
Basically DH has a scheduled appointment. We've been bumbling along assuming mum would look after the kids and she has assumed I will be looming after them? I have my own life, child and job to deal with she has a few hours here and there and they are HER kids!
Am I being totally unfair here? Should I be the one who takes time off for their kids?
