Feeling your pain. Both my girls have just gotten over their coughs - DD2 had it for 5 weeks (ended up with an ear infection at 4 weeks so was prescribed ABs) and DD1 had it for 7 weeks and also ended up with a really nasty ear infection last week (7 week mark) so was also put on ABs. Our GP said the infections were most definitely related to their coughs. Something to keep an eye out for if the cough really lingers like my girls coughs did.
