Rooey, hope things have settled down for you. I hope you were all able to get some rest this weekend.
The cabbage leaves have been used for years and do work, your Mum will probably say this as well.

Yes, if it hasn't improved by now go to the hospital. DD1 was about the same age as yours when I got it and I was a hospital case, was saved from actually going as we were away and had 2 nurses with us.
Does the hospital have a LC attached to it, if so go visit them, as others will tell you well worth the visit.
