DD sometimes makes strange noises like squeaks & horse grunting noises. It is mostly after she nurses. I'm wondering if it's reflux because I can hear gurgling up & then its kinda like shes struggling to get her breath. Maybe I'm just kinda nervous because she was on oxygen for 6 days after she was born since she was 3 1/2 weeks early. I have her sleeping in the carseat. Now she is on my chest & not making any noise whereas she had been in the carseat sleeping & making those noises for half an hour. Any ideas? Thanks!
