Have I mentioned how awesome holidays are to encourage speech and language? Here are some ideas to get the most mileage out of Halloween in the next few weeks.
A bunch of these ideas capitalize on activities you will be doing anyway...why not add a concentrated effort to boost speech and language along the way?
Point out decorations and label them - "I see a bat!" "I see a black cat!" "Look, that witch is flying!". Easy first words to practice at this time: Boo! hay, bat, cat, light, whoo (as in owl sound), eyes, nose, mouth, apple, etc. Narrate what you see on walks, while shopping, reading books, or at parties. It never gets old when you're two :)
Also most of the following ideas apply to toddlers as well, but keep in mind that toddlers are very young, they learn through play...keep things fun!
Practice the trick-or-treat routine, have the child review with you (great for sequencing). Talk about Halloween night safety and practice making predictions/asking wh questions (ie. What would you do if a house doesn't have it's lights on? Why do we wait until Mom checks our candy before we eat it?) Also practice having your child say thank-you after getting a piece of candy! That is an important social piece of the routine.
If speech is a concerns really hammer the sounds in "trick - or - treat" because they can be quite tricky. Other good phrases for speech (particularly k/g sounds): piece of candy corn, decorate the cookie, put a candle in the pumpkin, look at the black cat, Practice saying the name of whatever costume your child will dress-up as, because you know they are going to be asked!
Do some Halloween baking! Follow a recipe to work on sequencing, quantities, and problem solving. Discuss what works and what you might change next time. Talk about textures, tastes, smells, and how something looks. Baking is SO GOOD for language development. You could even take pictures of the various steps and then have the child use them to tell a friend about their fun activity (phones make this super easy).
Compare/Contrast different Halloween icons, how are a pumpkin and an apple alike, how are they different? How are a bat and a witch alike? How are they different?
Explore at the pumpkin patch, on a hike, at the park, on a walk in your neighborhood. There is so much to see, hear, smell, touch, etc. at this time of year. Bombard your child with descriptive language! "Look, that pumpkin is so smooth, but it's stem is super prickly!" "Let's see how many different colors of leaves we can pick up before we get home." "I don't know why leaves get crunchy when the fall off the tree, let's go home and look it up."
Think of some "Would you rather?" questions to play with: "Would you rather eat a caramel apple or bob for apples? Would you rather carve a pumpkin or paint a pumpkin?"
