mother
母 centers on the concept of a mother: a female parent or maternal figure.
母 is a pictograph of a woman with breasts, representing a mother. The modern form retains the stylized shape of a kneeling or standing female figure with two dots indicating breasts.
The two dots inside the box-like shape represent breasts, and the overall form suggests a woman's body. Picture a mother nursing her child: 母 is mother.
For ボ, imagine a mother gently saying 'bo' to her baby, like a soft, comforting sound: bo -> ボ, the sound a mother makes.
