Yes!!! Repitition, repitition,repitition!!!! They need that. And stick to the same schedule. It becomes a habit fot them. So after doing that for a while, they know what to do. For Luigi its about 20 mins after eating that he knows he has to go out, so now he goes to the door to wait for me. Same with play time. And when we say "Time for bed," he runs to the door!!! Because that is what we used to do all the time.
Wake up- We's pick him up and take him out
eat- 20 mins later, we'd pick him up an take him out
play- same
So just keep being repetitive and stick to your schedule!!! Soon you won't have to tell her, She'll tell you!!!!
