My reply was so long and detailed I ended up just PM-ing you. The bottom line is that we loved the language experience and also hoped that it would work out until 5th grade. But we've been dealing with issues of asynchrony from late K until now, 2nd grade, and have utilized a variety of educational options over the last year consisting of primarily English instruction supplemented with French tutoring. The language and cultural experience is invaluable, but in my experience it doesn't really slow anything down except the development of each language, and only for a little while. When we had DS tested in K his language scores were too low to qualify for his current program, which could have been the dual-language lag or it could simply have been the 5-year-old wiggles. Regardless, a year later his scores were closer to where we expected and he is loving his new HG school.
