I have read lots of posts and the different opinions are interesting. However, from some of the difficulties being described, together with that of my own/friends/families, I'm doubting whether it ever can! I realise that if you have successfully and happily blended your family, you probably wouldn't post on MN, but from talking to friends/colleagues/family who are struggling as SP's, it seems to come down to a) widely different parenting attitudes, and b) the fact that people just cannot feel the same about other peoples children as they do about their own! Anyone, agree/disagree?
