If I had to pick a "must-have" toy for a child, puzzles definitely would be at the top of my list. Puzzles have been around for years and still continue to be very popular with all age groups, ranging from toddlers to adults. Puzzles are making a comeback this year, judging by the large number of puzzles I spotted at the Toy Fair in February. Here's why puzzles are good for your kids.

I am glad to see puzzles back in the limelight. My girls love them and so do I. There’s nothing like putting a fun puzzle together with them. It is great family fun and really keeps there little minds going. I’m sure we’ll be buying even more!
I’m excited and happy that puzzles are the rage again. A game that encourages concentration and logical thinking, how great is that! I also noticed that kids who grew up playing with puzzles had control over their emotions, they become patient and very dedicated. My kids all time favorite puzzle is the under water and the US map which I got from http://www.simplykidstoys.com/creative-play-puzzles.html and there are more puzzles you can choose from. I especially love that all their games are toxic free and safe for kids.
