We have an only child and we do not regret our decision at all. I knew soon after having her that my family was complete.
She is turning 13 in December, has always been very strong willed. She is turning into a very nice young lady (now ask me that in a half hour and I might have a different answer, HA) Of course there are ups and downs, we just deal with that the best we can. We are going through the hormonal stage right now and it gets downright scary.
I know people say she is spoiled and I will admit that there is nothing she does without. We realize that she needs a lot of interaction from different people. Some people would never know I have an only child because I usually have 2-3 girls at my house on a regular basis. I encourage her interactions (good and bad) with her friends so she can grow and mature.
We've talked to her about a sibling and our choice to have only one child. She is quick to say she likes things the way they are. She comes home from sleepovers where siblings are around and she tells us she is glad she does not have to deal with siblings. I realize most of those with siblings cannot imagine being without them. She can't imagine having them.
Everyone is different. Health reasons were also a part of why we stopped with 1 child. Good luck and enjoy your son everyday. My "baby" is growing up way to fast. She is already talking college and excited about it. I am excited for her as she starts that part of her life.
