I am bottle feeding and he goes three hours in the day up until around 3pm when I feed him 2 hourly but try to stretch to 2.5 hours so I can get the last feed in at 10ish, routine for feeding goes roughly as follows on a good day!:
2am, 6am, 9am, 12 mid, 3pm, 5.30pm, 8pm, 10.30pm
I try to treat 6am as night feed with him still swaddled and lights down etc but he remains wide awake and read to play!!
