Sorry Lydia hope you have a better night tonight.
It seems to help when Josh has something to visualize, like the ball of yarn you use.
When we were at swim class one day I was trying to tell him that I would like to stay for the whole class (he sometimes wants to leave early) because if we left early that would be like paying for a whole cheeseburger and only getting half. That made him laugh.
In other swim news we went down the street to his friend's house today who has a pool and he didn't really get in but he did get on one of her inflatable toys and sat on it in the pool.
