He knows where the kitchen is. It does not take a degree in rocket science to make a sandwich.

I got sick, bad sick with bronchitis/pneumonia when my daughter had nust turned two. I was pretty out of it on meds.

When she couldn't rouse me enough to fix her something to eat, she went and made herself a peanut butter sandwich and made me one too.

She was two. That's how common sense works.
