First time mum looking for a little advice from the more knowledgeable 
4 day old DD, EBF, some minor latch issues which we're working on but very alert, good colour, happy, plenty of wet and dirty nappies (colour has changed to orange this morning)
Milk came in on Saturday evening and seems to be plenty of it, weighed this morning and she's only lost 4% of birthweight (was 8lbs 15ozs at birth) so midwife happy.
Am feeding on demand but she has no real pattern yet, today:
Midnight - 20 mins
01:45 - 30 mins
05:00 - I tried to feed her but she wasn't interested and just looked a nipple with mild amusement (not distressed in any way)
06:00 - 20 mins
07:10 - 10 mins
07:40 - 10 mins
09:30 - 15 mins
Sleeps well between feeds and is still asleep now having gone straight down after feed.
Should I wake up or just trust her to feed herself when she's hungry given there are no weight issues as such.
If it makes an difference, she has gone 4 hours between feeds 3 times in the last 48 hours (including this morning) and then fed regularly for a few hours.
Sorry it's long and thanks for any and all advice
