Just wanted to say hello and how glad I am to have this section of mumsnet!
I'm currently 33 and pregnant with my first dc; I'm 21 weeks and we just found out it's a boy. I guess I had a fleeting moment of "what about all the pretty dresses" but I'm pleased we are having a boy. If he turns out to be half the man my husband is, he'll be amazing!! 
Well, anyway, I know that this will be our only dc but anyone I've told have been a little, "don't be so silly" in their response. Result is, I'm not going to mention it again as it's no one else's business!
We are married for twelve years before we decided to try for a baby, so I guess that's part of my reason, age but also I don't just have an inclination for a big family.
I think about all the cliches, onlies are spoilt, can't share, attention seeking, will be lonely but I think that's remedied by parenting.
I don't know many other parents of only children, so it's nice to have this board.
I enjoy reading the posts and they certainly help me with my concerns!
Thank you!
