Where's One and Done to answer this one? I have one child and I don't plan to have anymore. I am a single mom and so many people say that I will meet someone and want more. They are probably wrong. I love only having one. It's like you said, there is the time. I can attend anything he needs for me and not have to worry. I feel like I would be unfair to have another (if I were in a place to) as I don't think I could handle it. I like just having one.
As for any negative stories about being an only child I don't know any. All I can say is that there is no promise that siblings will be close. I have 2 and we don't talk all that much. No animosity, but we simply are not close.
It's hard for you right now b/c she's only 2. My son is 6 and in school and it is GREAT. I nanny for a 5 month old baby and his older sister and I can't imagine having a baby. They are fun, but wow... we've gone on some field trips and I forgot all the gear you have to bring!!! It solidifies the fact for me that I don't want to do that again.
Since my son is older we are planning vacations and things we wouldn't be able to afford if I had more kids. There are many pros to an only child!!! I hope other Mamas have great advice for you!! Best Wishes!
