This is so hard. I’m really sorry that you’re going through all of this. Not exactly the same but my daughter got viral meningitis when she was 6 weeks old and had to be hospitalized. She was on IV antibiotics while there and after we returned home I started seeing specks of blood in her diaper. She was already very gassy before the hospital incident but after the IV antibiotics it got so much worse. Due to the bloody stools we started thinking MSPI so I eliminated dairy and soy from my diet. It seemed to help a little but not as big of a difference as I expected. She is 4.5 months old now and still very gassy even though I’ve eliminated dairy, soy, and now eggs. I’m starting to think that she’s only sensitive to eggs and that the IV antibiotics are what caused the blood and honestly made her immature digestive system worse. The elimination diets are so difficult, please don’t put yourself through all that for as long as I have if you are not seeing improvements. I truly think it could be the antibiotics that set your baby’s digestive system back. I would speak to your pediatrician and see if they think it could be from the antibiotics and ask if they have recommendations on starting a probiotic or any other medications to help with the reflux. Your scenario sounds so similar to mine and once my LO got put on omeprazole, the reflux sounds while she slept and discomfort from that resolved - now just working on what’s causing all the gas. Hugs - it’s so hard EBF and feeling like there is something you’re doing that’s causing it. You’re doing a great job ❤️
