Puzzle

Nellie has been doing puzzles for as long as I can remember.  At 2 and 3 she was doing 25 piece puzzles and at 4 doing 50, 5 doing 100.  She has mostly been doing 100 piece ones since then.  For Christmas she got this 500 piece Noah's Ark puzzle (http://www.dowdlefolkart.com/products/56-noahs-ark-puzzles.aspx)  Just this summer she decided to start it.  She has been working on it for over a month and is this far already.  She won't let anyone help her and actually gets mad if you try to help.  Puzzles are really the only thing she will sit for a long time and do.  This one will be one that we glue and put on the wall.  She impresses me every day with what she can do.
