Out of its depth, the neighbourhood watch

Beware of dreams and other idle thoughts.
To this or that one they confide
the wonders of a great cathedral nave,
impart the inspiration for a masterpiece
in paint or sound, and on occasions have been known 
to disclose all the workings for
some new break-through machinery. 

By contrast, on the likes of me they lay
the burden of dark secrets not to be disclosed --
secrets I  would treat them well to be without.
Their latest confidence, bequeathed
through thoughts that I was not controlling at the time,
but letting them run free, was clearly worked out
in advance, before they saddled me with this:-

We have a squad of killer babies in our town.
There is no doubt. Coincidences come
too frequently. And each time I've been steered
their way to see. First time: across the square
a row of trampled snails... and there, six yards
beyond the row, a fluffy toy, a tiny, woolly lamb.
So, not convinced? Try this for size: next thing,

a hedgehog in the roadway. Dead, of course. The gardener,
who lives across the road from me, has said
it died of some toxicity -- and not a hundred miles away
a baby's dummy lay. What better instrument,
I ask, for one so young to use for poisoning?
Then just this last weekend, a fox cub we first saw
in spring... found in the gutter. Bloodied. Head bashed in.

This was the babies' top-most topping yet --
they still have not, to my uncertain knowledge, struck
an actual person dead. No doubt they're working up to it!
But now, apologies... the fox... how do I know? How am I sure?
Not fifteen yards away, a baby's plastic rattle. Split 
from top to bottom by the blow! And so, each escapade 
becomes more vicious than the last.

It's true I have not seen these killer babies yet.
Imagine them to meet at night, but have no clue
how they achieve these meets. Maybe the birds
are utilised... the cell is organised through tweets --
but that does not explain the no doubt ultra-strange
logistics of their meets. How could small babies manage 
them? And what are parents doing at these times?
