I had that issue previously with my LO. At first I thought it was the bottles, changed bottles and teats but still the same. Then I thought it was the milk, tried giving her at different temperature but it was the same. In the end, we found out that it was reflux. My LO was hiccuping daily, spits out milk after every meal though little. But the pronounced thing was she would start to cry whenever she saw the bottle or when we try to position her in the bottle feeding position. She latched on really well at night. Anyway, we bought her to her PD and sought treatment. She's now drinking well, 120ml every 3 hrs. Also, we burp her often and sit her up for 15 mins after each meal. Does your LO have the same symptoms? If so, might be worthwhile to seek advice from a PD.
