Toddler with pain in stomach

alexandra

So my soon to be 3 year old son hasn’t been eating so well. So yesterday saturday we did a cook out and he was eating a peace of sausage, and then all of the sudden he starts saying ouchie ouchie and he would grab his tummy and was starting to cry, after rubbing his tummy he then threw up ! ... then today like around the same time (9pm) it happened again he was eating a piece of pizza and did the same thing, grabbed his tummy and started saying ouchie ouchie and then threw up ! His tummy was kinda hard.. it worries me :/ also he has had diahrrea for about 3 days.. tomorrow morning i will be taking him in to the Dr. idk if any of your kids has been through this ?? And what might it be ?
