Im a step mum myself and on a scale of 1 - 10 (1 being horrendous 10 being blissful) my relationship with DSDs mum is probably 3/4.
My daughter is 5 and her dad is now with a lovely woman after a string of crappy, trashy girlfriends.
She is making a real effort with my DD and I am most greatful.
Having experienced a difficult time from DSDs mother I am aware of never making this woman feel uncomfortable or pissed off about being a stepmum... but of course I still need to air grevences with DDs dad as he's a bit of a cock and needs reigning in often (a lot)
Any tips on how I can (not be her best friend) but make sure that mine and step mum's relationship is positive?
