Ethan is 12 weeks old today Last week slept from half 8 until about half 5 for 3 nights in a row, but for the last 3 nights he has woken up nearly every hour. Last night he slept for 2 hours solid and that's all. He is not waking because he is hungry as he is only taking 2 oz thru the night but won't settle back to sleep. He doesn't sleep a lot through the day either and I have no idea what to do with him. Please help, I have tries everything I can think of
