Hi there

We have a 6 month old baby girl who was diagnosed with severe reflux at 8 weeks. From what you described, it sounds like possible reflux to me. Our little one was the hiccup queen and had the majority of symptoms except she was thriving. She would scream from morning till night. Everybody said it was colic but I instintively knew it was more than just colic. Eventually at 8 weeks, we were referred to a paed (we lived in the UK at the time) and the paed diagnosed reflux. Since then we have been on medication and prescriptive formula as the paed thought she may be lactose intolerant as well. A week after the new formula and meds, our little one was a different baby!
All the best
