I LOVED being an only child and if I have kids I would want to stick to the one. I'm extremely close to my parents and was all through childhood, had plenty of friends and I slotted into their lives so well we managed to do lots of exciting things my whole life I know we couldn't have done if I had had more siblings! Don't resent it one bit! If I have kids, I want one so I can give him or her the same quality I had myself. - At least, I'd plan to only have one, anyway! I know oopsies can happen haha.
