Caught Red-Handed With Cookies

I just caught my 3-year-old munching on the last cookie I hid behind the fridge. Now he's got crumbs all over his face and is trying to tell me it wasn't him, but I know better! His little pouty lip and big puppy eyes are melting my heart though... Should I be mad or just give in? I think I'll let him have a few more tonight since he won't admit it. Hope the hubby doesn't find out!
