DS2 has never needed as much sleep as ds1. However sleeping through the night has become the exception rather than the rule. He goes to bed at around 6.30-7pm and will usually wake at sometime between 3am-5.30. If it is earlier, he can usually be settled quite quickly with some water and a cuddle - he may wake again and he may not. This morning it was 5.30 and he then refuses to go back to sleep. He is in the same room as ds1 so we haven't ever really tried controlled crying. He does have a dummy. He is quite happily watching teletubbies now but will be really tired by about 10am, have an hour sleep then not sleep again for the rest of the day. Does anyone have any suggestions?
