I cannot rate these highly enough. I had no choice but to buy one, as they are essential to allow you to participate in Waterbabies classes, however I am so glad I came across them. They cost £8.99 plus £2 P&P from www.splashabout.net, and Waterbabies also sell them.

They fit snugly over a disposable swim nappy (although they can be worn without one) and are tight (but comfortably so) around the tummy and legs providing a fantastic seal stopping any nasties from escaping. Despite the snug fit, they are surprisingly easy to get on and come in a range of bright colours and designs for boys and girls. We have had the fish design, the stripy and the plain ones in all sizes as baby has grown.

After using a Happy Nappy I would not feel happy taking him in without one as I have yet to find anything else that seems as though it would do the job as well. Far better than baggy shorts on a little baby in my opinion, the nappies are good quality and one of my best baby purchases. I recommend them to everyone!

I bought some surf-style swim shorts for going swimming outside his lessons with a built in nappy and they were never worn. I much prefer this nappy to any other swimming nappy. They can also be worn comfortably under a wetsuit in cooler pools, which is what we do when we go to the local leisure centre.
