Thanks I have just got us a swing. He seems ok in it for about 10 mins but then he cries again. Perhaps it is just that today was all a bit much for him. I will of course keep trying. I am desperate for this to work!! Even 20 mins of him quiet in it would be bliss!!!! he was overtired I think when we tried to get him in. So maybe that was a factor!
Thank you for all the encouragement, as you know some days as worse than others.
