I don’t officially endorse or work for any of these companies… These are just a few of the toys and websites I use in my daily treatment of 0-3 year olds 
I am a strong believer that you can use the toys YOU have in your house to stimulate language development…
Oh my gosh… how all of the little tykes love this toy… I frequently hold the balls in my hands and cue or wait for the child to make a communicative gesture like “ba” for “ball”, “mo” for “more” or use of a sign to request… It’s such a simple cause-and-effect toy that grabs all of the kids attention! [Words I target with this toy include: more, ball, more ball, give me, up, down, ball up, ball down, my turn, I want, counting and colors...]
A simple barn with farm animals is great to target animal names, animal sounds and location words. I frequently with-hold the pieces to encourage the child to request more pieces. [Target words: more, cow, boo, pig, oink, duck, quack, horse, neigh, up, down, on top, give me, I want, chick, cluck, sheep, baa...]
Yup, just your run-of-the-mill bubbles.. They grab the attention of ALL children (especially those with special needs!) and are great to stimulate requesting (ie., “more”, “bubbles”, “bubu”, the “more” sign..) [Target words: more, bubble, give me, I want, pop!]
My favorite are Melissa and Doug, but any simple puzzle with do. Puzzles are great to build vocabulary, request (I with-hold pieces to get “more” or “give me”) and identifying. [Target words: more, give me, I want, and the names of objects pictures on pieces]
