DD1 suffered reflux as a baby while breastfed. When I switched to formula at 5 months it settled right down..
Now that we have been introducing cows milk for a month or so she hiccups after each bottle. It sounds like her reflux did in that you can kind of hear her bringing the milk up and down each time she hiccups.
Would switching to a different type of milk help? When she has her nighttime formula bottle - she is fine.
