Kids and Moral Agency

We were having some sort of discussion where the idea of a "moral agent" came up, and Lily asked what one was. I described the idea, including something along the lines of "if it hurts you is that it's fault?", and then asked her what counted. Her answers, with my ordering:

• Rock: no

• Ocean: no

• Tree: no

• Ants: no

• Pigs: no

• Monkeys: no

• Babies: sort of

• Morgan (9m cousin): sort of

• Felix (18m cousin): in between

• Oli (3y cousin): yes

• Anna (4y sister): yes

• Ruthie: yes

• Fairies: yes

• Anna pretending to be a baby: yes

I'm curious whether adults would give the same answers, or whether adults would typically consider moral agency to start later?
