M.M.
OMG I'm SO dealing with this!
My DS (also 3) seems to selectively choose who he's trained for...which leads me to believe that I'm doing something wrong.
For our nanny, and others, he goes just fine all by himself.
The second that DH or I are with him, it's messes all over the place. I'm guessing that we're not being consistent enough. But I have to PUT him on the potty every 30 minutes, otherwise he just refuses to do it for us.
So frustrating. Wish I had suggestions for you.
I'll be watching this for others' suggestions!
