Hey A.,
I know that your extremely busy so I will keep this brief. I separated my boys' twins now 17 (Thank God) at about age 3ish. This is wonderful for them. They learn how to be independent & their own individuals selves. I feel that this is very important. They each will have their own personalities & tastes even though they share the special twin to twin bond. One will be dominant the other submissive, the list goes on & on. As with every child you have, no two will be alike.
Hope this helps. Have a great Mother's Day!!
