Recces for a cute day with 9m old?

Aside from Yarnton Magic Garden, are there any cute looking places for a day out with baby and his buddies? We do all the baby classes etc throughout the week, so looking for something you can drop into / turn up at that is also nice for us parents! Now LO is moving, nice little cafes are trickier because he isn’t entertained as much Would love any ideas please Thank you!!
