"They spread their little trinkets on the ground" is them leaving toys all over the place.
"A hundred fabric figures in a pile" is stuffed toys
"Tiny doors For walking through" is referring to comically small doors made for kids.
"While sticky fingers clutch forbidden things" kids touching things that you don't want them touching.
"Sinking ships On a foamy sea That roll and tumble slowly from the motion of their filthy Little hands" playing with toy boats in the bath.
"In the dark
When their eyes are wide
They listen to the secrets that I tell
In a ball
On their tiny beds" telling stories before they go to bed.
"beneath them where the shadow people dwell" monsters under the bed
"And the moon Beams that split the night Leave bars of yellow pasted on their faces As they drift into a dream" Them falling asleep.
