SJ Paddy does the same thing. He sleeps from about 9pm till 5.30 but will cluster feed in the morning and in the evening. I've been training everyone in the family not to go in on the first cry because often he's not awake and will sleep for another hour. The other morning I put him in his cot (he still sleeps in his hammock) to play safely while I got ready for basketball and he went off to sleep. Hopefully he'll start self settling during the day because atm I can't put him to bed unless he's asleep.
