We used to go a lot when the DCs were younger - my Dad lives nearby. When we last went there were lots of things for little ones - the Mermaid pool was good. (That link won't go straight to the right page - you need to click on Leisure Park & then Small kids)
It's a gorgeous site too, in a deep wooded valley, with a stream running through it.
When we first started going it was still a working farm - the farmer's wife was a friend of my mum & they started it as part of the EC's set aside scheme for farmers to do other things with their land. The first slides & ball pool were built in the old barn - I don't know if the original
Death Slide is still there - this was 5 years ago DD was 12 then - she's the one in the blue sweatshirt. Is it still there Enid or is it all modern & plastic now?
Not that I'm recommending the death slide for your 1 year old btw! I think DS was about 5 when he first went on it. He says he's never found one as smooth - the plastic ones are never as good. I've never been on it btw - I have no shame in admitting I always chickened out!
