Here are Mr. B's most played with toys from ages 2-3:
Imaginext
Mr. B has two sets that he plays with all the time: the Fire Station and the Pirate Ship. These sets are very large and expensive but they do get a lot of play. We rotate toys constantly and the pirate ship is the only toy consistently kept in the playroom because he plays with it almost every day.
Toobs
I have been adding Toobs to all of our unit studies because Mr. B loves them. They are excellent manipulatives and make learning so much fun. Some of our favorite Toobs are The World Landmarks Toob (Mr. B still sleeps with his landmark toys), the Coral Reef Toob, the Space Toob (which started it all) and the Presidents Toob.
Dress Up Clothes
Mr. B is ALWAYS in costume and his dress up box has become very full during the last year (thanks to thrift stores and Halloween sales). His favorite costume is of course his Darth Vader mask and helmet. He also loves to dress up as heroes (batman, superman, firefighters and police officers), construction workers and, recently, Harry Potter.
Weapons
Mr. B has collected a plastic arsenal of weapons. He has enough swords, light sabers and wands to conquer a small imaginary kingdom. These are probably his favorite toys of all because he goes completely crazy for them (the promise of a pirate sword got him to use the potty after months of refusing).
Lego/Duplo
Mr. B always ends up building himself more weapons out of Duplo (mostly elaborate laser blasters). He also loves Lego and recently started putting together the junior sets on his own. He loves the larger sets too and one of our favorite activities is putting them together. I buy Lego all the time because we all love it and are constantly building.
12 Piece Melissa & Doug Jigsaw Puzzles
The puzzles with the wooden backing are perfect because Mr. B doesn't have to work on a flat surface (he can also bring the puzzle to me to show off his work when he's done!). The bright colors also make the pieces easier to put together. 12 pieces seems to be the magic number for the last few months because he gets overwhelmed with more difficult puzzles.
Dinosaur Digging Kits
Vehicles
Mr. B loves getting and playing with small cars (especially the cars from the Cars movies). I find these very cheap at thrift stores (about $3 for a bag) and give them out as special treats. Mr. B has amassed quite a few. He's recently started watching YouTube videos where these cars are raced on ramps so that may be what he will start asking for soon.
Sidewalk Chalk
Figurines
Mr. B loves imaginary play so he treats his figurines like family members. They go everywhere with him. We love to get the sets at the Disney Store because they are based on his favorite movies.
Little People
Mr. B has been a fan of Little People since he was a baby. I keep a huge container of these in the garage and get it out for him several times a month. I am always looking for more pieces at thrift stores. They are perfect for hours of imaginary play.
Sports
Mr. B received a T-Ball set for his second birthday and played with it every day. He recently received a baseball mitt and loves to play catch. He isn't crazy about riding bikes but loves his scooter and Little Tikes Cozy Coupe.

Other well loved toys include musical instruments (like his harmonica), the Green Toys Rocket Play-set and anything that his sister is currently playing with.
