Will they cope, because kids just do?
I have 3 kids and want them all to go into the French system. They are currently 3.5, 2.5 and 7 months.
Due to a lot of boring policy / bureacracy, the children are likely to only enter a full French education when they are 6, 5 and 3. We are going to try to do it earlier, but we're unlikely to get them in to any Lycees in the UK because we are not French nationals, etc etc. We will apply, but I don't think it will work out.
However in 2015, when DD1 is 6, we will move abroad and will definitely be able to put her into a French school. Is this too old for her to go in - it is cruel to just expect her to pick it up, or am I underestimating childrens' abilities for languages? She would then stay in the French system until she finished her education...
If you think she could pick it up, how long would it take for her to be comfortable in French? A few months? A year? Or would she never sound properly native because of the late start?
Both DH and I are English speaking only (well, DH might say he has passable conversational French) and obviously this will be the only language spoken at home.
Thoughts?
