Just to make sure those wanting to become parent don't get things too wrong. Having a child is a choice most of the time (if you are OK with contraception). Therefore, since it will effectively replace yourself by your child in your life equation, be sure you want the little kid. If you want it, then it'll feel much easier (but not completely easy nonetheless, the OP is right about 75% of your spare time disappearing :-)). If it's a choice for you and your lover, then it'll be ok and bring a lot of satisfaction. But having a child is usually not the good time to start this new business you dreamt off :-)
Right, totally, and I've got three of the little devils so clearly I'm not entirely down on the experience, but having a kid could well be the single most stressful (and possibly expensive—childcare or having one partner stay home is really really expensive) event/decision in an HNer's life for a variety of reasons that aren't always obvious to non-parents. It's no picnic.
Damn! Three ! You must love that :-) I'm more than happy with 2. And besides, 3 means that there are more kids than adults in the family :-) It's like playing a football game with on player excluded :-)
(but as I say, if one chooses it and feels like being a parent, I can guarantee a hell of satisfaction, those kids are just marvelous eyes openers)
