DD1 2.7 has nasty cough, when would you take to docs?

[ChirpyGirl]

I know there is not much they can do if it is just from teh cold but it has been going on for about 4 or 5 days now, she is coughing in her sleep really badly (even making really lovely scary whooping noises on occasion) and refusing cough medicine.
Any advice? any home remedies? (apart from paracetemol as that is not helping)

I am hesitant to take her in but would you if it stays more than a week?

have you tried medised? coughs are normally bodies way of clearing all the badness and can take ages to leave mine took 2 weeks but if too concerned take to gp incase turning into croup or slight chest infection best with children to get it checked as can so easily turn into something else

Can't get medised as I took DD2 with me to buy it and they refused to sell it to me!
(Can see their point but still!)
