I can't remember the timings of everything now, so I may have this wrong. My previous post from 2011 was about 6 months before my twins started school. So at that point I had definitely taught them to read some English, using the resources mentioned in this thread. Once they started school, I left them to concentrate on the German. I did still read to them most nights, but they started to want to read for themselves. They did read mostly in German for that first year of school but then when they were 8 they wanted to read Harry Potter and we only had a few of the books in German so first one child, and then the other started reading in English without any extra help. The only issue that one daughter had was the pronunciation of names that she had never heard of, like Pamela. I bought them lots of books in English, and we got lots of German books out of the library and they are both excellent readers (although one is not so good at spelling).
