Words that start with "BA" sounds

Lately, everything Sam's been saying starts with a "ba" sound.
Let's see, we've got his favorite, which is basketball, all the way to baseball, balloon, and banana, followed by words that are similar, like bottle and bubble.
Of course, they all sound similar to "ba-ba" and so we've got to listen for little differences in his voice that lead us in the right direction. For instance, if he extends the first syllable, we are pretty sure he's saying basketball. If he gets fussy and it's not meal time, he wants us to blow bubbles. If he is hungry, he's most likely asking for a bottle unless he recently saw a delicious banana nearby.

Those are just some clues in case you are confronted with a talkative Sam in the near future. :)
