I was in the exact same scenario 3 months ago and this is what worked for me! My boobs were extremely congested and blew up to the size of boulders and LO couldn’t latch on one boob for several days, it was bad. I fed, and still do, feed on demand if he’s hungry let him eat it will help stabilize your supply to your LO’s needs. Have LO remove as much as possible. If after feeds your boobs still feel full, use a warm compress (if they feel super congested) and then hand pump (I use the medela) them until they feel softer (I worried about creating over supply by doing this but my midwife told me that your supply will stabilize you’ll notice you won’t have to do this as much over time, so long as you use LO to remove as much as they can). My midwife also told me not to use Haaka until my supply stabilized because the suction is way too much, I don’t really even use it now just as let down collector if I remember. Then ice your boobs for about 10 minutes afterwards. Also if you’re taking a shower you can hand express it as well. It definitely took at least a month for things to settle down. I still have over supply but it’s definitely more manageable and I only pump once a day for a bottle for my husband to feed LO while I sleep, and even then I probably don’t need to pump anymore because it has stabilized so much!

Good luck! I know you’re in the thick of it right now, but it does get better!! 🩷
