Hi J.,
Your 4 year old sounds like my 2 1/2 year old son. If and when you get any helpful hints, I'd love to read them. I'm like you, I've tried every angle and nothing seems to work. I'm frustrated too.
My email address is ____@____.com if you get any helpful hints.
Thank you very much and good Luck to you!
S.
