spitting up.

Hannah
My ebf newborn spits up a lot. It's not a huge amount at a time but after each feeding. And she is fussy after eating.  The past two days she's started really spitting up a lot. It happened twice yesterday and once today so far. I think she might after acid reflux but I'm not sure. I will be calling her doctor Monday morning but I just wondered what other mom's think it could be.
