I am sharing with you all, a wonderful geometrical multi-dowel stacking toy puzzle that’s good for toddlers & preschoolers! Here’s the link to the video of my son, Moksh solving it! http://youtu.be/l-vkfpA_dnk
There’s another one like this which I guess is available on Amazon. Here’s the link http://youtu.be/oyuoE7Xd0N4
I bought it in Brazil from Tok & Stok store. They do have their website. I have not really seen it anywhere else in US or in India or even online. If I do, I will keep you updated.
I found this Chinese branded puzzle at the department store the other day and my 14 month old Caleb really enjoys it. Sorry ladies there is no name its in Chinese bit the block are all shaped like snow flakes.
Puzzles can be great for children. I started my younger one on puzzles from here at about age 3 http://www.jumpstart.com/parents/worksheets/logic-puzzles-worksheets Before that I bought puzzles in a variety of materials for my kids as they were growing up - metal, wood and plastic. Both my husband and I spend time trying out a variety of puzzles with our kids.
