I have the same problem. Sometimes she'll nurse for 20 minutes, but we fight the whole time. She's pulling off, making a face like she has to burp. I try to burp her for a few minutes and she starts fighting so bad I have to give the breast back. Sometimes she stiffens up her body or she won't open her mouth big enough to get the whole nipple in. I spray almost every time she pulls off the breast at the beginning of a feeding. She gets the hiccups a lot after feedings. Sometimes she is asleep and then as soon as I lay her down on her back she starts making uncomfortable noises. As soon as I get her up she calms down and will usually hiccup or burp a few times. Then it takes her a while to calm down and go to sleep. Does this sound like OALD? Any ideas on what to do? Some nights are better than others, but it often causes me to lose a lot of sleep.
