B and S

Natalie is learning the letters/sounds B and S in school. With LMNOP, B is Bear and S is Stars.

Some book ideas for this:
The Little Mouse, the Red Ripe Strawberry and the Big Hungry Bear by Don and Audrey Wood
All I See Is Part of Me by Chara M. Curtis

We have always used a capital S to mark Steve's water bottles and told the children it was a snake, so you can do Snake -- some people also use Stream but then I don't know what you would do for R (usually River).
