Sorry I didn't get back to this earlier. I did come on, with a headache, and read the thread last night but my headache got worse seeing the number of replies .
Thank you to thedolly and others (only remembering the last names I read) who understand what I mean without trying to twist my post into a hatred of single/blended families. And GoodWitchGlenda who put it down so well.
My motives are only that I want to protect my child from what she doesn't need to know now, when she hasn't (as far as I know) come across the situation to ask about it. NOT single/blended families but quite simply the situation in the story (where a parent doesn't seem to have any interest in their child). When she comes across it in life then yes of course we will deal with it, but my issue is, should she have to learn it first from a book which is not even written for her age group? I don't think you'd see many books for 6 year olds which explores the topic of parents leaving their children? Yes it is a reality in life, but so is child abuse, and domestic violence, and so many other things that people wouldn't want their 6 year old reading about.
And I'm about posters who think that my OP somehow translates as not wanting my child to mix with children from single parent families. Seems like some people like feeling victimised for no reason.
The book is part of her reading homework, not a library book and it is just one chapter from Crummy Mummy and Me. The one where she goes looking for her "very own, real, biological father" or something like that as part of an assignment at school. The name of the book is called The Family Who Won a Million and Other Stories (well something like that) and the other stories have been fine.
Anyway, I've taken on board everything - even the criticism. I have come to the conclusion that it is quite possible that in my dd's innocence she could potentially say something quite hurtful to another child sometime. So I will not be letting her read that story now (sorry but it sounds really screwed up to me, she can read it later) but I will talk to her about the different types of families, including those where a parent is not in the picture.
