I would also recommend Chee's baby sensory classes. You get lots of great ideas for baby activities you can do at home. Chee is a great class leader and both young babies and older babies enjoy the activities (different themes each week keep it interesting for mum as well!). Plus you get a 'play time' break in the class so your baby can play in the ball pit etc which is fun and makes it good value as you get a whole hour of activity for your money!
