I am in the thick of it now with my DD so I really do not know whether it gets better or not. I just try to take a step back when I get frustrated and understand my daughter more. I love the following quote. I read it often and to me it explains so much and helps explain to some degree where the meltdowns (and messes in house) are coming from. Good luck and hang in there!

"The truly creative mind in any field is no more than this: A human creature born abnormally, inhumanly sensitive.
To him...
a touch is a blow,
a sound is a noise,
a misfortune is a tragedy,
a joy is an ecstasy,
a friend is a lover,
a lover is a god,
and failure is death.
Add to this cruelly delicate organism the overpowering necessity to create, create, create - - - so that without the creating of music or poetry or books or buildings or something of meaning, his very breath is cut off from him. He must create, must pour out creation. By some strange, unknown, inward urgency he is not really alive unless he is creating." � Pearl Buck
