Don't spend lots of $$ on baby toys - I really don't think it's worth it. You can make your own things as suggested.

Orange bags stuffed with plastic supermarket bags for a good tactile/noise toy. Coke bottles with rice/pasta. Mini M & M tubes etc etc.

Plastic toys are crap anyway - they smell, give off gases and are expensive to boot. Wheres the love??!

I'm going to post a very good article I read about plastic toys later today.
