From the NHS website:
" Children up to the age of three should use a smear of toothpaste with a fluoride level of at least 1,000 ppm (parts per million).
After the age of three, they should use a pea-sized amount of toothpaste containing 1,350-1,500 ppm of fluoride.
Children should be supervised when brushing their teeth until they are about seven".

Welsh Water don't add fluoride to your water simply because the West Midlands Strategic Health Authority hasn't asked them to do so:

Welsh? West Midlands? Herefordshire seems to move around a bit!
