We stayed in a lovely hotel in Eastbourne last summer with our then 2 year old. It's a hotel but rooms have a kitchen so you can prepare your own food. Really child friendly. No pool but very close to the beach and other attractions in the area. http://www.theguesthouseeast.co.uk/

I've just got my little boy some Splats,waterproof like wellies but light-weight and breathable. Only trouble is they start at a size 8 which I bought for my son who's a 7 thinking he'd wear thick socks but they come up really big. Anyway might be worth a look. Bit expensive at ?38 but worth it if they are in them constantly. http://www.thesplats.com/

These are brilliant for babies,and lightweight so good for posting. marthalewisdesign.co.uk

I have a boy so it may be different. We use an eco brand called Beaming Baby,they are absolutely the best nappies I've used in terms of absorbency. And I was a nanny for 20 years before having my son,so have used many of the usual brands and tried lots of other eco brands too. I buy them in the Fourways Pharmacy in Herne Hill but I think you can get them in the health food shop on Lordship Lane,sorry can't remember the name.
