Hi I'm not sure whats been happening with my baby but he sometimes drools alot or has some spit up and I think he might be breathing it in by accident, he looks shocked has wide eyes and his arms jerk a little when it happens then he breathes a little faster or coughs, has this happened to anyone else? I don't know whats going on, it lasts a few seconds then he's fine but I'm quite worried it happens most days is it normal?
