Sealife centre in Birmingham (on the train from Kiddi is about 40 mins) - you can prob get vouchers etc with nectar points.
Museum / centre for child in central library in Brum, have a look at
http://www.birmingham.gov.uk under the events section. There is also milennium point, which has the free science museum, lots of touchy feely tons of stuff to do for kids there, and it's all free.
If you have a car there is Bewdley, Severn Valley, Safari Park, lots of parks all nearby, google is probably your best bet x
