tonight I did a couple of WI/WO's, but then when he started to look settled I sat next to his cot and just said sshhh, sleepybyes. He was looking really sleepy around 8 with very heavy eyes, but then he resisited. I sat next to his door and ignored him, but he could still see me. Eventually after he started being silly I told him to lie down in a very firm voice and he did and started to chill. I sat next to his door doing sudoko and didn't say anything else. He finally fell asleep at 8.45. Much better than we have had the last few nights.
My OH and I decided to have our dinner first so we weren't feeling hungry and ruining food while trying to get him down. I definately felt calmer.
Good luck ladies.
