My son had an ear infection last year and the PD gave him antibiotics after checking his ear with that little torch thing, so definitely bring your child to see the doctor as soon as you can because they need to confirm it's actually an infection first. A few of my mum friends also mentioned their kids got ear drops prescribed, but it really depends on what the doctor finds when they examine, so best not to wait and just book that appointment at the polyclinic or your regular PD.
