Come up with a swear-word alternative. When your children reach mimic age (a dangerous time), having a neutral word to use in place of cursing comes in really handy. My advice, start training yourself to use this word when the baby is born, so when you hit mimic age, you are ready. I have a few different ones, but "fudge" gets used the most. I should probably come up with a more inconspicuous one.
