I have only just realised what is going on. He has been complaining of a pain in his throat for a few days now but I only twigged when he rushed for a drink of water to try and make it go away.
I can't give him a rennie/gaviscon, it is for over 12s. I will take him to the doctor but is there anything I can give him in the meantime? I have propped him on pillows and given him some milk but he is still suffering.
