Thank you both of you for your kind replies. Time has moved on since I posted and in particular I have, thanks to Chad's kind advice, spoken to the senco at SGS who is just wonderful and the decision was a no-brainer! We went on a quick visit to meet her last month and DS is so comfortable with the school. Greatly looking forward to coming along next Sept. And if any other Ealing parent is reading this and would like to car share, please let me know. There are two families interested in setting this up next year.
