One of my all-time-favorite gifts that my kids got for Christmas was Imaginets by Mindware from amazon.com. I love how these puzzle pieces are magnetic, so no more puzzle pieces everywhere or random pieces lost in your house! My daughter is 3 years old, and I thought Imaginets was perfect for her age. She surprises me with accomplishing the harder puzzles that I thought she’d have some difficulty with! Any toy that shows they’re using their brain is a great toy for me!
