Double trouble

I am the younger twin of an identical set of twins - in fact we are mirror image twins with me being right handed and my sister left handed. Amongst other things, we both have moles on the same spots on our faces but hers are obviously on the opposite side to mine. I am younger by a whole four minutes. She has three beautiful boys and add my two then we have 5 children between us. I read somewhere that our children are not cousins but genetically they are siblings. Interesting me thinks....

This is us, taken by me with my sister's camera in her office :-)
