after ds mmr last week we had two bad nights with him not wanting to sleep till 12 and waking up at 9 , normally he is a 7 to 6 sleeper. For three nights running he has slept 7 till 8.20 on the dot! I am wide awake by 7.30 ready for the day and sorting myself out where as before i was dragging myself out of bed and puttin ds in with me for 20 minutes whilst i woke myself up properly. I feel great. I doubt it will last but now i know that it wasn't the light getting in ds room that was waking him up so early!
