     The cost of raising a child from birth to age 18 is about $ 160,140! That doesn't even touch college

tuition. For those with kids, this figure might lead them thinking how much they could have banked. For

others, that number might confirm the decision to remain childless.

     But $160,140 isn't so bad if you break it down. It translates into $ 896. 66 a year, $741. 38 a month, or $171. 08 a week. That's a mere $24. 44 a day! Just over a dollar an hour.

     Still, you might think the best financial advice says don't have children if you ever want to be "rich".

It is not.

     What do you get for your $160,140?

     Naming rights.

     Giggles under the covers every night.

     More love than your heart can hold.

     Kisses and hugs.

     Endless wonder over rocks, ants, clouds, and warm cookies.

     A hand to hold usually covered with jam.

     A partner for blowing bubbles, flying kites, and building sandeastles.

     For $160,140, you never have to grow up! You get to finger-paint, carve pumpkins, play

hide-and-seek, and never stop believing in Santa Claus. You have an excuse to keep reading the

Adventures of Piglet and Pooh, watching cartoons , going to Disney movies, and wishing on stars.

     For $160,140, you get to be a hero just for taking the training wheels off the bike, and coaching a

baseball team that never wins but always gets treated to ice cream regardless.

     You get a front row seat to history; to witness the first step, first word, first date, and first time

behind the wheel.

     You get to be immortal(不朽的).

    You get another branch added to your family tree.

    You get an education in nursing, criminal justice and communications that no college can match.

     In the eyes of a child, you rank right up there with God.

     You have all the power to correct a mistake, scare away the monsters under the bed, patch a broken

heart, police a party, and love them without limits, so one day they will, like you, love without counting

the cost.
