My son is also late in doing things. He still is not walking independently and he is 3 yrs 3 months old. He also had a year of early intervention and 8 months of speech therapy. but it has taken his mone time to get talking. What they told us was to start simple. Break things down into categories. Start with things she will know easily. Rooms or places in the house. Take her to each room and say where are we? We are in the ____. We used Kitchen, living room, dining room, bathroom, mommy's room, Roberts room, porch, basement. Try to get 8 to 10 rooms and keep working o things in this category for as long as it takes for her to master them. Keep labeling things and telling her that you are doing as you do them. Another easy category to work on is Bathtime vocab. Bathroom, bathtub, facecloth, soap, towel, shampoo, lotion, boats, ducks, water. Then say "look, we are filling the tub!" What goes in the tub? water?" Get her to repeat the words after you. As you wash her get her to tell you what you are washing too. Another good category is clothing. Shirt, socks, pants, shoes, dress, hat, jacket, barrette, etc. (stick to 8 to 10 words in each category.)
I hope this is a help for you. It really helped my son. the other thing we did was make flash cards for every word in our list for that week. (it took my son about a week to master each list.
If you have any questions let me know, and I will be happy to help.
