How many more?

I've been reading Dr. Laura Schlessinger's book Ten Stupid Things Men Do To Mess Up Their Lives I quote a section here that had me in tears.

"My listener David has two boys: Jonathan is five and a half, Nathan is four (July 1996). The following was inspired by a night when David, before going to bed, checked on his two sons who were aslep in their beds. Jonathan had fallen asleep on the floor, so David lifted him up and tucked him into bed, kissing him good night. Nathan, upon being relocated, awoked slightly and asked Daddy for his teddy bear:

How many....

How many nights do I have, God?
How many nights do I have to tuck each of my boys into bed with their teddy bears?

How many times do I have left, God?
How many times do I have left to lift my boys up onto my shoulders before they are too big?

How many more kisses, God?
How many more kisses do I get to give my boys after I've tucked them in at night?

How many pushes, God?
How many pushes do I get to give my boys on a swing befoer they out-grow it?

How many days, God?
How many days of hot summer do I have left to run through the sprinklers with my boys?

How many more tears, God?
How many more tears of joy will I shed at the end of each day that my boys have grown through?

How many more times, God?
How many more times will I get to lify my boys back into bed once they have fallen out?

How many more years, God?
How many more years before they come and lift me from the floor after I have fallen?

How many, God?
How many?
