Oh yes my son is very strong! He tells me every day

( its because he eats his vegetables of course)
I shall try him again tomorrow and get him to count and do the excersize in just one direction to start with, then I might ask him if he thinks he is clever enough to drive up the mountain and then back down, we may have to jump a few rivers or skip over a few pot holes ( to stretch) but I am sure we will get to the destination in time.
I think today he felt a little intimidated. It's the first time he has ever sat on the chair, usually he stands to play with the keyboard, and it's a high stool, also I think I need to sit next to him, not stand behind him. We may just start by being at the keyboard together banging keys until he will accept some gentle guidance. Or I could just catch him in his " I can do anything" mood then he will fly through.
Oh I just had another great idea I can get his sister to show him, he loves her so much at the moment he won't even go to preschool because she is home on holidays

I will let you all know how I go
