I love this website for toys for my preschoolers: www.forsmallhands.com. It was recommended to us by our eldest daughter's teacher back when she was little and we still love their toys and materials. They sell a lot of wood toys, practical life toys (miniature brooms, kitchen gadgets, rakes), and sensory toys (toys meant to be taken in with all senses). In particular, I love this alphabet book and these construction toys.
If you like shopping in person instead, one little toy store I love is within Franklin's Store located within the Restaurant. It's a little whimsical old-fashioned toy store that has tons of wood and eco-friendly toys. They hardly have anything that's just plastic and noisy. It's on my way to visit relatives so just fyi, its a bit of a drive (in Hyattsville).
Good luck. Shopping for toys is fun if you're in the right store (ToysRus overwhelms me!).
cheers, Cristina :)
