I was wondering if anyone else had experienced a slow let down whilst BF. It can sometimes take about 5 minutes for my little guy to get the milk to come down, I have tried expressing before I feed, but I am now struggling to even stimulate my let down when expressing. I have also just started to take fenugreek to help stimulate my milk production, which seems to be helping a little, but this has been an ongoing issue with my DS, he is currently 7 months old. Any ideas would be appreciated. Thanks
