We go to waterbabies, and went last year too. Waterbabies say he should be wearing a disposable swim nappy plus a 'happy nappy'. And then his swimming costume (all in one thing) over that.
Now, the sizing is tricky to work out on the waterbabies website, so I went to Tesco and got, for £3, an all-in-one swimming trunk and built in nappy combo. Will this do, and do I also need disposables underneath? The built in swim nappy looks like rubber knickers (or whatever they're called these days) basically. Don't seem to have anything absorbent in them. But I'm trying to avoid disposables because I'm a cheapskate worthy.
Is there any etiquette here?
