DC 6 was poorly 2 weeks ago with a fever for a week which turned out to be strep a, they finished their antibiotics at the beginning of last week and has been fine since but today they’ve been lethargic and sniffly and fever has returned. I’m worried is it normal to get ill again so quickly? Could it be strep again? I’m such a paranoid mum about my dcs health as it is and I’m starting to panic!
