United Kingdom
Wetsuits for kids in Devon and Cornwall are cheap, they don't need top of the range (usually £35), just get the cheap ones (probably £10 or less). They give them sun protection, keep them warm if they are in and out of the water all day and give a bit of added buoyancy when they are learning to swim.
Get the ones with short arms and legs, you get more use out of them when they are growing fast, but remember to sun cream the lower arms and legs, or do like my kids do and wear a long UV sun suit underneath. Watch out if it's hot, especially if the kids are not going in the water much as they can get very hot with the black neoprene absorbing the heat.
They were the best things we ever bought, my daughter learned to swim in the sea when she was 4 in hers as she felt so confident.
You can buy them in surf shops (expensive), but also in most beach kiosks, bucket and spade shops in town and also in some supermarkets in beach towns. The ones from Decathlon in France are really good, and only 10 Euros.
A beautiful long beach which has places to eat and is a brilliant place to see a sunset.
Newquay
Situated between Newquay and Padstow, this large sandy beach is a welcome escape from the tackiness of nearby Fistral.
Watergate bay is not just a lovely spot; there are facilities to hire all sorts of equipment for fun in the sun: surfboards, wave skis, power kites etc.
After a hard day's activity you can chill on the beach with a beer listening to surf rock.
A popular location for the English Surf Championships and since my last visit a certain Mr Oliver has opened a restaurant there.
A beautiful spot none the less.
