Baa vs baa

Yvaine likes this set of board book very much. She will read the whole set beside me before bed. Her literacy rate is up to 80%. Bravo!

Tonight, as usual, she brings the box & sit close to me. I was holding my tab, playing wordfeud; at the same time listening to her reading. Suddenly she asked me, "mummy, why the baa, baa are different? One Baa has big letter & another baa use a small letter?"

"hmmm...." thinking if she can understand if I were to explain to her.
"oh, I know. The big Baa is for the big sheep & small baa is for small sheep."
