Oh I totally agree. It is hard to think of life as an only child. I grew up with 2 brothers and we spent so much time playing together...holidays were always fun too. So it is hard to understand what an only child will experience, but obviously they are happy and experience different things while growing up.
My delivery was horrible...everything went wrong (but the final outcome was a perfect daughter, so well wroth it!), and the first 16 months was so hard. She cried non stop for months and months, so still doesn't sleep, she is quite demanding and almost bossy now! But things are getting fun now...what a little personality!
Anyhow...I miss work, and I honestly don't know how long we can afford to have me not working, so I think #2 will most likely not happen...but I will say you never know!
