"Its give and take.."you give, they take.."

At least it feels like that sometimes, autistic kids appear selfish, or at least mine do..i want food...i want juice....sometimes i feel like saying i want a hug and a kiss...i want to be acknowledged as your dad, by you...and your not getting juice until you do....it would be great to say it and see a reaction....but i wouldn't get one if i tried, they would look at me and say it again "i want food", "i want juice", i love my kids, but it feels at times that i am/we are a means to an end for them, they want something we give it and they learned quickly that this is the way it works... i don't know if other parents feel this way, but i know there are moments when they can break your heart with the most unexpected act of love you've ever seen, and when those moments happen everything else goes out the window, you literally jump off a bridge for them, and it really does make it all worthwhile, sometime i wonder to myself do parents of a so called normal child take moments like those for granted ?
