Hi, I have a 2 week old. Whenever she wakes or fusses I put booby in her mouth, if she wants it she'll take it. Can be any time, even half hour after previous feed, or 1-3 hours.
For night feeds I wait for her to grizzle (she hardly ever cries!) since I'm in deep sleep I need her to wake me hahah. For the past couple of days she cluster feeds between 8pm-12 and then feeds 3-5 hourly at night between 12am-8am. Sleeping through means sleeping for 5 hours so I guess she's getting there but I'm not fussed...she'll do it when she's ready
