A combination of these are going to get the best result.

Breast stimulation is the MOST important and effective way to have a good milk supply.

Deep Latch - If you don't have a good latch you won't remove milk well and hence your body know to make enough.

Feed Frequently - Feed 2-3hrly during the day; no more than 4 hrs overnight

Double pumping after a feed - 10 mins straight after MOST feeds. The Bellema Euphoria Plus is great at Increasing Supply

Power pumping - This is when you pump for ten minutes, rest for ten minutes, and so on, for a total of 60 minutes making up the ‘power hour.’ (This can be done a few times a day.)
