We have good and bad days too. We stopped Infacol and did smaller more frequent feeds (feed every 2 hours) which has helped us have more good days than bad now - baby is 17 weeks, also on omeprazole xxx
So glad to have found this because it’s been making me question everything when she has a good day!
Common but not normal sadly. Look at how you’re feeding - does baby have a big, wide, deep latch?
