wait and then fix

children cost loads and, if you can't afford them, will ruin your life

don't take that in a nasty way though, it's just that you have to think about what you are earning, what the mrs is earning, what the mrs won't be earning and what the kid will cost to run, the days off you will have to take when the kids ill, the sleepless nights, the cost of getting the initial baby thigns sorted as well as the on going costs such as nappies, wipes, clothes, etc
