Ds has just turned one. He had a teeny bump on his tummy as a newborn about an inch above his belly button that would come and go. Tonight he ate a huge portion of dinner and his wee tummy was obviously quite full so I noticed the bump above his belly button was back and sticking out. Does anyone know if this would be an umbilical hernia and if so what happens next? We're at the gp on Friday anyway so will mention when I'm in. It's not noticeable and I can't feel it normally, only when he's crying very hard or very full.
