When DD was born breastfeeding got off to a bad start for several reasons. In hospital she went 5hrs+ without waking for a feed at one point on day 2 and the MW had to cupfeed her some formula as she seemed too sleepy to think about latching on. When we left hospital on day 3 I was told I must wake her at least every 4hrs and feed her, so I demand feed her but set alarms at night to make sure doesn't go more than 4hrs. She is now 6.5 weeks old, and I am wondering at what age we can go to truly feeding on demand and she can sometimes be left slightly longer, especially as she is cluster feeding usually from 7ish to 12ish and does sometimes want feeding more than 4hrly at other times too.
