Alexandra F.:  What I love most about this magnetic building toy is how it inspires kids to be creative by building - and testing, and improving - structures they can actually play with once they’re done. Unlike other magnetic building toys, Squaregles actually hold together well without randomly collapsing, and the set comes with fun pieces like ramps and towers for making things like castles or racetracks. It takes a little practice to master putting the pieces together, but even my three year old loves building with them, and my older kids (and me!) get a kick out of trying out new creations every time we play.

Jennie Utsinger:  This gorgeous hand-carved rainbow offers endless play possibilities. It's one of those perfect versatile toys for 4 year olds, but delights kids of all ages - and grownups too!

Sarah Calamita:  A train set is the perfect gift for kids who like to build things! Your 2 year old will spend hours connecting trains, putting pieces together, learning colors and shapes and just amazed at everything that comes with a train set!

Kelly R:  This high-quality set features cool trick pieces that kids can use to build an endless assortment of domino races.

Alexandra F.:  These chunky bricks have been been used pretty much constantly in our home for the last 15 years, and are one of my favorite open ended toys because they can be used from such a young age and still be fun to play with even when kids are ready for the smaller LEGO sets. A couple of building plates, a set or two of classic bricks, and a few DUPLO figurines have been some of our most played with toys these last couple of decades.

This block set is equipped with built in magnets which means they won't fall down as easily and are perfect for little curious hands. The blocks allow for pattern recognition, problem-solving, and imaginative play as your little one grows.
