I have a 17yr old girl, 13yr old boy, 7yr old girl.
"If you are supposed to learn from your mistakes, why do some people have more than one child?" - I don't know who said this, but it's somewhat true. ;)
My personal opinion: Live is a crazy adventure filled with highs and lows. Live it to the fullest and take the pleasure out of it where it exists.
Children are a lot of hard work. At the same time, they really challenge a person and make life interesting. If you want children, have them. It will hamper your life in some ways, but make it more interesting in others.
There is a good chance that you will have a baby boy. 50/50 at least. ;)
Remember the first one is the beta test. The second child is your chance to raise one right. :D
If you have 3 children, they can gang up on you. ;)
If you want a child, go for it. Do your best to raise them well and tell them you love them everyday. :)
