I've been in a blended family for 13 years now and I am continually amazed at the judgement from some Bio Parents, a vocal minority(I'm hoping), expressing judgement over LOVE, specifically in reference to the Mom/child relationship I share with my Step Kids.
The notion that love between a parent and child is somehow wrong, disrespectful and/or disloyal to a Bio Parent if the love exchanged is between a Mom and kid has a Step or Bonus attached to it - drives me mildly insane! Insane because STEP or BONUS doesn't change the feeling of love or its legitamacy between the parent and child.
I could ramble on about my relationship with my Step Kids, specifically my two youngest and all the reasons why sharing the parent/child relationship is a good thing for everyone involved, but I won't! Instead I'll talk about my own daughter who was thrust into a divorce and blended family situation by no choice of her own.
