How do I start building my stash now? I'm exclusively direct latching and I'm not able to express enough after lo latches on. Maximum volume I can express is 50ml after he latch. I'm gg on trip in early September and I have only 10 packs of ebm now

Some of my friends shared that pumping in the morning helps. They feel that their breast is fuller in the morning. Some try to squeeze in an additional pump session when baby is down for the morning nap. Not sure if this will work for you, but worth a try. Also, drinking plenty of fluid and trying different milk booster may help increase the supply as well. Good luck!!
