Hi mama, Many mamas find that the best way to increase BM supply is by directly latching. We measure input by monitoring baby’s output: if baby is gaining weight well and producing a minimum of 4-5 wet diapers a day, you’re doing splendid. To maintain milk supply, milk should be removed once every 3 hours - 8 times in 24 hours. Pumping at night is also beneficial as this is when your oft produces the most amount of milk. You could also increase milk supply by doing the following: 1) power pumping 2) skin to skin with baby 3 ) have a pumping or direct latching weekend with as much rest, water, food and Netflix as possible :) Here are some great articles: https://www.medela.com/breastfeeding/mums-journey/low-milk-supply https://kellymom.com/hot-topics/low-supply/
