All Tired Out

We were invited to visit my cousin L today and her little girl I who is 2 and a half and her little boy C who is the same age as the twins.

The girls had a great time, taking out all their toys, and generally making lots of mess. I don't know what relation if any the kids are to each other? If we are first cousins what are our kids - second cousins? Anyone know?

A lovely day was had inside, just as well as it was pouring of rain outside today.
