After months of worrying DS1 did fantastically on his residential school trip. Ok so he stood and told me all about it looking in the other direction, but hey you can't have everything ;). He joined in all the activities - zip wire, canoeing, gorge walking etc. Apparently it wasn't even him keeping everybody else awake at night!! He ate the food - although one night it was yucky and he had to have salad instead.
Can't believe how relieved I feel now. He can't wait to go again next year :)
