Please and Thank You

I'm trying to teach Nolan 'Please' and 'Thank You'. This is no easy task. We finally have Please down, which is more like 'Peash' when Nolan says it. After days and days of asking Nolan to say Thank You when I give him something...he finally says it today twice!! Woohoo!! So I said, 'Your welcome, Nolan' both times. Now when I say...'Nolan we need to say Thank You', he says 'Your Welcome!' DAMN! We got all of that backwards!! Oh well.
