Toddlers should have Reins

It really doesn't take much brains
To see that toddlers should have reins
Which have the great advantage that
They help to see they don't get fat.
Instead of sitting in a pram,
They can gambol like a lamb,
Safely held so they can't stray,
Getting exercise each day,
Which will help to make them strong,
Being active all day long.
There's also something else that's true,
That they'll become more tired than you,
And when their bedtime comes around,
They'll close their eyes without a sound.
