Another option is to skip the puree thing altogther and go with baby-led weaning. I did the puree thing with my oldest son and then changed to babyled weaning for my twins. Have to say baby-led was so much easier and got them eating a wide variety of normal foods (no pureeing required!) much quicker.

There is loads of info available on the web, here is just one site:

It isn't some way out approach, highly recommend it.

Happy to answer questions if you are interested.
