I need to correct "him"

It started off as Digby, Paige, and I... we weren't even out of the front yard and Digby went right back to his backyard!

Paige and I's conversation on said walk...

M: Paige do you see that bunny?
P: Yes, him cute.

M: Do you see that butterfly?
P: Yes, him orange.

M: Do you see that bird on the wire?
P: Yes, what him doing up there?
M: I don't know, I think he's watching us.
P: Why him watching us?
M: He doesn't know us.
P: Yes him do! Me Paige and you mommy.
M: Yes, but he doesn't know us.

P: Mommy, I'm sweating. Lets go home.
