[Deegan's mom]

Ok, I give up. Since I've got Deegan about a week and a half ago, he's been constantly eating or chewing on things when he's supposed to be going pee. He gets so distracted when I put him out to potty by having twigs, mulch, helicopters from the trees, worms etc, etc in his mouth. And recently he's even been eating poop and it's grossing me out!! Not his own poop though.
Why is he doing this and how can I get him to stop???
