Congratulations to your daughter.My son was learning disabled too.... Reconsider your thought to take a trip to a waterpark for two reasons. First, if you get a gift that is tangible, she can look at it as a reminder that she can accomplish things.It doesn't have to be an expensive gift. During the inevitable down times, a present that she sees will remind her how she earned it. Second, it rewards the whole family ( I am assuming that the other kids get to go, too) for HER accomplishment, which makes it less special. Try asking your daughter what she would like to do to celebrate. Even if your other children have things you want to celebrate, have it be separate occasions. Whatever you do, do not forget to keep celebrating every good report card. If you start to get used to them, and forget to keep encouraging, praising and celebrating, your child can "forget" to keep trying so hard. Never forget that it is harder for a leaning disabled child to get a B or an A than it is for the average child to get them. It is a huge blow to a child who had worked very hard for something to hear," Oh, that is what we expect from you." I remember hearing that from my parents,(after working really hard) and feeling all my pride is my acheivement and all my good feelings disappear like the air from a deflated balloon.Good luck. My leaning disabled child graduated from college this Spring. Your daughter can get there, too.
