So yesterday had had 2 1.5 hour naps. BT was 6.45pm. He did his usual NW's and then was up at 5.20am, did a poo etc. Had a nap at 7.15-7.50. Then 9.30-10.55 then 1-2.45 (had to wake him up for the school run) He managed really well with the long A time before bed. Just wish he'd wake a bit later in the morning!
