Went to petting farm yesterday with three-year-old son, was religious about hand washing due to e-coli and various infections, signs up everywhere warning to wash hands. Son is very accident prone in the sandpit he managed to jump forward and somehow get loads of sand in his mouth. I tried not to go into worry overdrive and washed his mouth out best I could with water. He has been complaining of tummy ache all day and I’m now very worried. No upset tummy today, but I’ve read up on it and it’s normally 3-4 or as many as 14 days after. What has me crazily worries is that I saw sandpits at farms are often a source. I want to take him gp tomorrow but I don’t know if that’s over reacting and if they could even reassure me this early?
