I am step mother to 2 daughters who I have cared for since shortly after their mother died when they were 5 and 7. They are now 13 and 15 and I have two other little ones now. I was wondering if there was anyone else in this sort of situation because it's very different to step parenting when both natural parents are alive and around. We are all happy and they call me Mummy but I can't pretend it has been a walk in the park and still find it a challenge sometimes. Also I think sometimes you think a situation is the way it is because I am a step mother whereas perhaps all mothers have similar stresses with their teenage daughters? Any one out there?
