I think this is the earliest there is. I was too young to remember how old I was, but I must've been about two-ish. I was still crawling on the floor every now and then, and I remember I found some piece of candy bar on the floor while I was under the breakfast table. I decided to be nice to my mom and I went over to the kitchen where she was talking on the phone, and I offered it up to her, making the sound I did to get my mom's attention. She took it while talking and she began to put it in her mouth. My mom sputtered and gagged, to my confusion. She had to put down the phone.
It turns out candy bars don't magically appear under the breakfast table, but dog stuff does. This is the earliest memory I'm left with, thinking about it; I don't know how proud I am of that aside from the fact I guess I can say I literally fed my mom stuff without even trying
