i was born with GERD, mine was serious enough that i ended up with a feeding tube and had to learn to eat. so i've dreaded Willow showing any signs of it. she's got some of the symptoms of reflux: persistent coughing and hiccups, chronic nasal congestion, irritable crying after each feeding, sour/wet burps, and some spitting up. she doesn't spit up very much, and she showed all the same symptoms when she was nursing (she's FF now). i've heard they can have "silent reflux" with little or no spit-up. i'd mentioned all this at her 1-month checkup, the dr. said as long as she's eating and gaining, she doesn't have reflux. but: she is gaining very slowly, and she eats *too much*. as in, when she BF'd she cluster-nursed pretty much all day, and now she is hungry for the formula every hour or even more often. i still have GERD and i drink something constantly, because swallowing helps ease the pain. Willow shows hunger signs constantly, but then shows signs of pain during or after eating a little bit. so i'm wondering if she has silent reflux. anyone have experience with this stuff? how do they diagnose it?
