Ants in their pants

They have:
Ants in their pants.
A fascination with the contents of their nose.
A strong desire to pull a loose thread from the t shirt nearest then.
An uncontrollable urge to scratch off, the scab on their knee,
And eat it.
To put the corner of their worksheet into their mouth,
And chew off tiny pieces like a mouse.
To suck their sock.
To rock back.
To rock forwards,
And back again.
To chew their sleeve, shoelace,
The end of their pencil,
And their own hair.
To roll around the floor,
Or flip periodically onto their tummies.
An innate desire to fiddle,
With something(whatever's in reach.)

They are children of six or seven.
Bless them.
