I took my toddler to the doctor about 6 weeks ago as he had been randomly bursting into sudden tears, grabbing his stomach and saying owwy tummy for a week or so. They gave him a once over and did a urine test and everything was fine and they sent us on our way. He is still doing it though, sometimes he'll go a day or so without doing it but he's done it a few times today. Would you keep pushing this at the doctors?
