I did not raise twins. But, for your own sake you do need some free time. Twins are hard even if they have no developmental complications. Put them in the same school so you can get a break.
My tired three year old would have napped every afternoon until she was six. But the school that was available and helped her the most it turned out with her speech development was the local non special one as she learned from the other children. She was tired when she came home but we learned how to cope with late afternoon snacks and an earlier bedtime.
