I Want To Do It Myself

Junior has to stiffen his arms to get his hands to move so needs hand over hand help with most activities. If he thinks I am doing too much and not letting him help enough he gets very upset.
I have one of his ipad boards set up with some general things he might need to say while doing activities or talking. Yes, No, I don't know, maybe, help me please, etc. To avoid his need to holler at me I recently added a symbol for "I want to do it myself".

Today we were putting together the solar system that his teacher gave him for Christmas(thank you Teacher Cindee, Junior loves watching the planets rotate and the sun light up). Junior quickly told me "I want to do it myself" when he started to feel he wasn't getting to really help.
Oh how I love the voice the ipad has given Junior.
