sonnet They brought their baby

They brought their baby by own faery will
It didnt smile or play at peekaboo
It didnt mug to mum on kiss and coo
If self absorbed its interest touched nil
They queried could I please apply a skill
I said I burgled no invaders knew
I stole in candlelight in light of lieu
I could arrange a changeling louevre or grille
The baby noticed stranger faces fawn
A strangers rattle pillow dolls and crib
He laughed to spittle strapped in strangers bib
All wept their babbling baby breaking dawn
They heard a changeling change across the fence
I swapped again the babies many pence
Chorus fence barrier wall
