Analysis of "What Will I Do"

I've lived so long falling over Dinosaurs and dolls on the floor,
I've stumbled over little cars and shrieked at worms dangling out of their hands,
I've kissed scraped knees and gave a listening ear when they needed to talk,
There's nothing they think I cannot do,
I've been their playmate and at times their confider,
I've operated remote control cars and ministered to aches and pains,
I've doctored during their share of chicken pox, strep throats, and tried to take their hardest bumps,
 But someday they will be grown and gone,
With no more soccer balls, no more Finding something everyone will love to watch,
I cannot believe it will come true but when it does, What shall I do?
