You don't need the 'night' in nightlight - we know it's dark you told us that in the first line of the second verse. Unless you are referring to the light a child may need to sleep with? Still you mention night again in line four - the flow would work better without the extra night.

Nice.

L4 seems there only for the rhyme.

I'm on the positive side here. Perhaps -memorie(s)- instead of night light. There's a subtle rythm in this poem.

I honestly love it, very catchy. here's an 8, and a myspace add.
