So glad to find this thread. It is a great way to vent as well as gain knowledge from others experiencing similiar issues. My DH and I have two DS's ages 12 and soon to be 7. The oldest DS has ADHD and the younger DS was diagnosed at 2 with developmental delays, which changed last year to MR. DS (7) has limitations in the areas of cognition, speech, some life skills (not interested in being potty trained whatsoever; however he will get on the toilet now without screaming)

, some social skills (he is friendly, but tends to want to play by himself), and requires physical therapy. Mentally he is about 2 1/2 to 3 years old. Setting his challenges aside he is a very happy and loving child. He smiles often and is pure innocence. My husband and I find ourselves greiving over the fact he may never leave home to be an independent adult. Our oldest DS seems to be maturing out of his ADHD; not so hyper now as much, but tends to struggle with concentration. He is in gifted and talented and was just inducted into the National Junior Honor Society. Our two DS's are very opposite of each other. We are so looking forward to our first trip to WDW this September, as many families of children with disabliites talk of how magical it is; and how their children seem to do so well in WDW and afterwards.
I agree with others who have stated parents of "normal" children seem to take for granted the normalcy. I currently am a foster care case manager and see first hand how some disabled children are taken advantage of or abused/neglected. I told my DH a few years back how thankful I am that God gave us DS (7) so at least he would be with a family who would support, love, nurture, and care for him; and his needs.
I commend you all for taking care of your children, while at the same time being human and needing a break.
