My 19 month old son Tristan mummbles, he only says a few choice words

[Guest guest]

My 19 month old son Tristan mostly mummbles, usually. His vocabulary

seems to be improving, however, it is progressing very slowly! When he

does say words, sometimes, they are not words that children should be

saying they are words that adults say. Tristan says the

usual:mommy,daddy, kitty, doggy, baby, bottle, ball, thank you, byebye,

brother. Now if he would only say:Please and up, I would be extremely

greatful! Is there any other way other than repeating those words over

and over again to get him on the path to saying those words?
