There is one month short of 21 years between myself and my little brother. I was raised an only child an I ALWAYS wanted a little brother or sister, it took mum 3 major relationships before she was ready to have another child. I didn't like being raised an only child even though I had loads of toys etc. My mum & stepdad (not her current husband) raised me in a very loving environment but I felt there was something missing. This is probably why I have always had it in my head that I'd like 3 or 4 children of my own. Funnily enough my brother is always asking for a younger sibling too but with mum's reproductive days now well over with its not going to happen.
