i used s2 and usually I'll pump at massage mode for 1min-2mins until ive let down then I'll switch to express mode. if i rmb correctly, massage mode i used lvl4 and express i used 46cycle at 8lvl. find the comfortable suction for you! bc everyone is different but massage mode is best to trigger let down to get more milk :)
Hi mummy, I'm using S1 too! Usually I will do 5 mins of massage mode then another 5 mins of mode 38. So far so good for me. :)
