I hope the poor little thing is feeling better. If not you might want to keep track of what she eats....we had to do this with my cousin's little boy. We made a chart and every time he ate something we listed it all and if he complained about his belly hurting and so on. We eventually narrowed it down to a few things that seemed to bother him everytime and took one of those things away for a week to see if he was feeling any better. After a few weeks we found out that anything containing tomatoes upset his stomach. Your little one might also have a sensitivity to something she is eating that is making her feel icky all the time. I hope she feels better soon!!
