So since I happen to be blessed with 4 kids I decided it automatically makes me an authority on the subject of parenting. (That's right, self appointed.)
Now, I won't say that you should or shouldn't have kids, that's an entirely individual decision. However, I will give you a glimpse of what life's like with kids, so that at least you have a perspective on the matter.
First, if you are a woman and have this dream of having a big family with at least 3 kids (just like I did as a child), be sure to find a partner that agrees with that vision, because let me tell ya, it requires patience and hard work, and though it has many perks, the marathon is long and breaks are not too many.
And I won't even get into the later years when they get older and require guidance and your friendship and lots of good advice. Right now I'm only talking about the younger years. Babies, toddlers, and preschool to first school years. If you have just one child, I'm sorry, but that doesn't count. Sure it's harder than no child but not nearly as challenging as 2 kids or more simply because of one word. Interaction. Once they start to interact with eachother (And they do. They interact the heck out of eachother since day 1) it's a whole other ballgame. And kids being the egocentric little creatures, ownership of toys becomes an everyday matter of discussion. (And by discussion I mean yelling, pulling, crying and the like.) Did I mention that semi deafness is a prerequisite to being a sane parent? But don't worry if you aren't. You will be, on the job. Just part of the whole "hands on" experience.
The other thing you should definitely consider is, that at least for the first few years (3-5 years for each child to be exact) you should forget about having Your Own anything. That includes, time, space or any possessions. What's yours becomes theirs, ipso facto. And they're not the most careful handlers. Just accept it. It'll be easier that way. On the bright side I guess you could say, that they make you less attached to material posessions :) yey.
They, however, are quite attached to material possessions. And nothing puts a smile on their faces quite like that new "thingie" you brought home that they can unpack.
Anyway, hope I haven't discouraged you when it comes to having kids because when all is said and done, I wouldn't give it up for the world.
