Baby Doesnt Qualify

My baby is 22 months but does not qualify for speech therapy at this time. Does anyone have any suggestions as to what songs/books/etc I can do with my baby that will teach:

- more

-milk

- on

- off

- under

& the other common words they should know.

I had an in home evaluation. They feel like though there is a delay, it is not severe enough. And since my baby is doing some things advanced developmentally (physically) and can understand what is being said that we should take the wait and see approach. If nothing improves with words, then they will give services. My baby cannot say the recommended amount of words yet.
