The Motherlode blog grappled with this, and while my emphatic answer was yes, as pointed out in the blog, many adult twins said they wish they had not been separated. My twins would have never wanted to be separated – they were 5 years old and they had spent virtually their entire lives together – so I am glad NYC DOE made this decision for me. As I said in my comments to the post, my twins made great strides apart, and though it is much more confusing for us as parents to deal with double sets of instructions and trips and worksheets that are similar enough to make one crazy, it is much better for them to be separate during the school day.
This is an amazing article on such a rare but very important topic. Thanks for sharing.
