Silent reflux?

I don't know if my LO has this or not. She seems to swallow a lot at random times and always gets wet-sounding hiccups. When she lays down in sleep she seems to struggle and squirm a lot more than DS ever did. She also chokes and wheezes sometimes. Am I being a paranoid mama and just assuming there's an issue? I've never seen this issue before. Anyone ever dealt with silent reflux? Does any of this sound familiar?
