The day my lo turned 20 months she put her first 4 pc jigsaw puzzle together. For a straight week she had me helping her 15-30 times a day. She worked so hard! She'll be 21 months in a few days and she can do her 4 pc, 6pc, and 9 pc jigsaws without help- and 12 pc ones with a little help. She is getting good at figuring out her 24 pc with my help, too. *proud* wink
