Before You Start Lessons
Once you have decided that the Suzuki method is for you then you will need to get various things in place before your child can start at the keyboard.
Firstly you will need to get the Suzuki Book 1 with CD (new international edition). The best way to do this is to join the British Suzuki Institute, and order from their shop as you get a discount with membership.
Other reading that is well worth the time are the books by Shinichi Suzuki:
"Nurtured by Love" by Shinichi Suzuki (link to amazon).
"Ability Development from Age Zero" by Shinichi Suzuki (link to amazon).
It is important that the child is listening to the piano CD every day! It will make it so much easier to when the child comes to learning the instrument if they are fully immersed in the tunes.
Your Suzuki teaching will start by teaching the parent. If the child already knows the repertoire via the CD it will make these sessions more informative.
