I think I have an over abundance of milk or fast let down on one side only. When feeding on my left my 2wk old splutters, coughs and pulls back on nipple and ends up with a shallow latch, no matter how good the latch is to start. We also gets windy and grizzly after feeding on that side and it takes ages to finish a feed, compared to right. The shallow latch is also beginning to cause some nipple soreness (that I'd finally healed after big latch problems when she was brand new). I unlatch and re-latch her multiple times, but it still ends up shallow.
Any suggestions? Should I block feed on the left - eg two feeds from left to every one from right? Express on the left side before latching her on? She's generally feeding every 2-3 hrs and takes about 10-20 mins on right but often closer to an hour on left.
