Starting to get worried about DD1 (age 5). She's had 3 bouts of what looks like the same illness in the last 5 weeks - v high temp, aches and pains and a bit of coughing. This is a really nasty bug which completely knocks her out each time and takes 5 or 6 days to feel better. Doctor reckons it's a chest infection and has just prescribed 3rd lot of anti-biotics which I'm really reluctant to give, though probably will out of desperation. ANyone else experiencing similar or any tips?
