My Exh dropped our son back after having him for the weekend, saying DS had been in pain since Saturday, to the point he didn't sleep during the night. Exh didn't seek out any medical help for him, just gave him one dose of calpol. As soon as Exh left, I took DS straight to the out of hours GP and long story short DS was admitted to hospital and had an operation 2 days later. He's now off school for 6 weeks. If the condition had been left, it had the potential to become very serious. Obviously this has rocked my confidence in Exh, who works in a medical role and should have realised the severity of the situation imho. As a lay person it was obvious DS needed to be seen urgently, and he's not a complaining child. My question is how to proceed from here? I don't trust Exh an inch now. How can I stop this from happening again?
