I read I Love Animals by Flora McDonnell, because 1 year olds love animals and the sounds the animals make.  We stopped on every page to make the sound of that animal.  We also stopped on the page with the sheep to sing Baa Baa Black Sheep.  (lyrics below)

Baa, Baa, Black Sheep

Baa, Baa, Black Sheep
Have you any wool?
Yes, sir. Yes, sir.  Three bags full.
One for my master, one for my dame and one for the little *love who lives down the lane.

(I changed the word from boy to love to include both boys and girls.  Please stick with any wording that you learned as a child, unless you want to change it.)
