Has a lack of, or an abundance of, siblings affected your personality?

When I was born, one of my two sisters was married and the other almost. My brother was older than both of them. So I might as well have been an only child. My father indulged me shamelessly and my mother considered me to be an inconvenience at a time when she thought she was getting her life back! I suppose she loved me in her own way but I spent more time at my sisters' houses than I did at my own, in the company of my nephews and nieces. I was never short of friends but always thought it would be nice to have a brother around my own age. Our only grandson is an only child and will remain so as DD made a decision not to have any more children. I respect her choice, but I feel for him. He has lots of friends but it's not the same thing as growing up with siblings. I've no idea whether it matters to him.

I was an only child without cousins or any other relatives my own age. I am independent, don't ask for help and find difficulty showing affection. After hearing of my husband's problems with siblings and reading about other posters problems I'm not sure I miss having them either.
Definitely gave me a tendency to selfishness which I try hard to curb.

I was in the middle for a long time. My elder brother was the first child and first boy grandchild so he was adored by all, I was a nuisance who happened along at the same time as mother caught TB causing her to spend a couple of years in a sanatorium in the depths of the countryside - my fault of course. My sister was born 10 years later and was a fragile little blond in sharp contrast to be the black haired galumping elephant that I was she became Poor * in my mothers eyes for ever. The 20 years after me came the bonus another son!! Deep joy- very very spoilt and turned out to be a complete wrong'un.

I am the eldest of three and can honestly say that my younger sister is the best possible friend I could have. We support each other when things are going badly and share in family celebrations. I wouldn't be without my siblings, especially as I get older and realise that 'blood is thicker than water.' Of course I realise that not all families are as lucky as we are. I recently read a thread about non contact between siblings and I thought that was sad.
