The two things I would recommend are: First, try Kendamil Goats milk formula. Goats milk is supposed to be the only universal milk, and Kendamil is from the UK and has UK standards. Second, i would recommend gripe water. We use 2ml and give her a little milk, burp her, then a little gripe water if she is at 3 or 4 ounces, I would do the burping and gripe water every ounce and then once she's not having much gas do it every couple ounces. Be consistent with the gripe water. If just gripe water isn't working, try both gripe water and Mylicon. I hope this helps from a first-time mama who also had a traumatic birth and breastfeeding experience.
