My 20 month old daughter has gotten into this phase where she screams constantly and protests sleep. Well tonight in an attempt to try to calm her down I gave her a bath. Before I gave her a bath, she threw herself on the ground, clutched her stomach, curled into the fetal position, and pushed her butt into the air. She repeated the same thing shortly after I got her out of the bathtub. My question is, could she be constipated, or could it be something worse? I just had my appendix rupture, and didnt realize it. Now Im afraid that it may be happening to her, and that I would have no way of knowing, since she cant quite vocalize whats hurting her.
