My days are in the summer,
when you'll eat me when I;m hot,
In fact I'll even eat myself,
Where battles tough are fought
But when you find me in a fight
'Twill be high in the sky
and if you catch me napping
I suggest you let me lie
When you're bad come to my house
From Ma get thoughts profound
Am I big or am I small?
Some say I'm just a pound.
What am I?
