Re: Its too hard
My 4.5 year old is like this. We talk a lot about "not giving up". I reward and praise for the effort, not the accomplishment. We make a very big deal about the effort and yes, we are excited when a goal is reached but again, it is all about the effort. He should feel he IS doing something awesome just by trying his hardest.
Sometimes she will quit and get dramatic about it and I walk away from the situation and let her know that she is welcome to try again, I will be really proud of her for trying her best and I cant wait to see her try again. Usually she will come back to it on her own if she doesnt have an audience right there supervising.
