4/5 mins during the day, her first morning feed and night feeds are around 10 mins long. She’s 7.5m but has been like this for a few months now
Usually about 8-10 mins in the day and I leave an hour between breasts giving her one at the start of the wake window and the other at the end
5/10 mins at a time, but it’s hard to judge because everyone’s flow / let down is different
