So I realized I definitely need to give a little more information on these spells. The doctors and nurses say they are apnea spells rather than choking spells. Although she coughed at the beginning of this one (and we'll see what the doctor says about it tomorrow), she hasn't been coughing in relation to her spells in general. And she isn't always pooping or having gas when she has them either. They do know that she has reflux, which may play a role in these. And she is aspirating milk (it goes into her lungs sometimes).
Because of her young age, all of these are things they believe she will grow out of. When she goes home, she'll still have reflux (we'll keep her elevated for a while after feedings and her bed will be elevated as well) and may aspirate milk as well.
Her main problem is that she doesn't pace herself when she's eating so she'll keep sucking past the point where she should have taken a breath and then stop sucking but forget to breath. They want to see her grow out of these apnea spells before she comes home.
Not sure if that helps, but I hope it does. If anyone has any questions, feel free to post them in the comments, and I'll try to answer them to the best of my abilities.
