Random lines from songs

Sam is singing songs, well at least parts of songs.  He will just sing lines here and there at random.   He was playing with the dog that sings and it was singing Itsy Bitsy Spider and he sang "down came the rain".  The music table played the color song and he sang "red, yellow, green".  He sang "l m n o p" with the fridge phonics ABC song; and he sang "roll them up" with me during Pat-a-cake.

He is saying more and more words all the time.  He can say about 70% of what we ask him to say but he doesn't have ways to use most of them in his daily life so it is fun to hear him say new things on his own.
