DS (7) needs to have a blood test and has got Emla cream to numb the area.
The lady at the chemist said to put it on, wrap the area in cling film and get the blood taken about an hour later.
The timing agrees with the information that has come with the cream, but it states to use a special dressing to keep the cream in the right place.
I'm happy that cling film will do the job, but does anyone have any tips that I should be aware of?
