My DD just started at a French school and she loves it! I love it too and my son of course wants to go. However, because it is a French school, he would be required to start reception this September 2017 at 3 years old!!! His bday is end of October and he will turn 4. This is because French system does by calendar year for bday. But bc the school is mixed half w kids coming in through British system lottery, they will be aged according to British age. If we were able to get in via lottery he would start September 2018, which we actually prefer bc he will be one of the oldest in class instead of the youngest. Pros to starting in September 2017 would bc he would be one year under his sister and they are super close and he already saying he wants to go to her school. The earlier you are exposed to second language the better. My sister was youngest in class and did excellent, so she says go for it. But my worry is he seems a little young to start reception! It's not really an option to get him in via the lottery, bc everyone applies and it's impossible. If we delay application, the would just put him straight into year 1. Anyone who has experience w kids being the youngest in class please share!
