Just wanted to say that I reckon it all evens out in the end, and if you've had a loving, secure childhood it doesn't really matter whether you're an only child or not - it's the security and love that's the main thing. I was a very happy only child, and although I think Mum got quite a lot of grief for not having two, I was very happy, made friends, and, to be honest, often looked at friends with siblings and thought: 'thank goodness I'm not arguing all the time at home'.
It boggles me that in this day and age, when we're lucky enough to have the choice about how many children we have, and whether we choose to stay at home with them, or work, people still hang on to the 'only child' stereotype. Especially now, when there are so many brilliant clubs and nurseries around, with lots of children creating friendships with others outside of the family unit. That's important, I think - the social aspect, but it's easy to find now without feeling that you have to provide siblings for company!
I think it's just great that we're in an environment where we've the luxury of choosing how many children we want - and be that eight or one, so long as we can provide nice food, cuddle them when they fall over, read books at bedtime, and all those lovely things, I don't think numbers matter one jot
