Still sorting out our new house and today it the first aid kit.  I looked up 'what to put in a home first aid kit' and found this answer under NHS Choices (http://www.nhs.uk/chq/pages/990.aspx?CategoryID=72&SubCategoryID=725):

A basic first aid kit may contain:

plasters, in a variety of different sizes and shapes

small, medium and large sterile gauze dressings

at least two sterile eye dressings

triangular bandages

crêpe rolled bandages

safety pins

disposable sterile gloves

tweezers

scissors

alcohol-free cleansing wipes

sticky tape

thermometer, preferably digital

skin rash cream, such as hydrocortisone or calendula

cream or spray to relieve insect bites and stings

antiseptic cream

painkillers such as paracetamol (or infant paracetamol for children), aspirin (not to be given to children under 16), or ibuprofen

cough medicine

antihistamine tablets

distilled water, for cleaning wounds and as an eye bath

We've always kept our first aid and medicines in our bedroom but, on reflection, what would happen if a visitor or house guest wanted access to first aid?  So now I've put it in the enormous bathroom cabinet (which would otherwise be empty as all our stuff is in the en suite to our bedroom).  

Having said that, many people say that more accidents happen in the kitchen than the bathroom, so that's the best place to keep the first aid kit ...

Here's another site (http://www.wikihow.com/Create-a-Home-First-Aid-Kit). It recommends having a container with two compartments: one for general first aid stuff and one for medicines for the family itself. 

On other sites suggestions have also included:

• torch
• cool pad (or could use a bag of frozen peas)
• burn cream (10 mins in cold water works wonders too)
