First Aid

Practicalities Health First Aid Readymade Kits 

Rather than laboriously putting together your own first aid kit you might prefer to buy one from one of the specialists in this field [Suppliers], though you will need to check the contents are suitable for your children's ages.

One benefit of a supplier's kit is that it will be well labelled as such, should customs take an interest in it.

Whichever you get, note that children are insatiably curious and may well find medicines which are not in a locked cabinet. Unless you feel certain yours will not be tempted to tamper you'll need somewhere safe, like a padlocked suitcase, to keep anything which could do harm.

Incidentally, if motoring in Europe a first aid kit in the car is compulsory in Switzerland and strongly recommended in Germany and Belgium.
