I have sent you details via a pm, but just to clarify, I have finally come to the understanding that whenever I have had EW's, overtiredness was a major factor. As well as W2S, I would get him to take a cat nap in the car about 9am, for half hour, and then he would take a longer nap about 12, and I found he fought it less. All these small things helped him overcome the OT's and he would then sleep later in the morning himself. Now when I start to have EW's I put him to bed earlier that night, it seems to nip it in the bud.
