old woman, grandma, wet nurse
婆 centers on an older woman, especially in a familial or caregiving role: a grandmother, an old woman, or a wet nurse.
婆 combines 波 (wave) and 女 (woman). The 波 component likely contributes the sound, while 女 gives the meaning of an older woman.
Picture an old woman (女) with wavy, flowing hair like waves (波). She is the grandma who tells stories by the sea.
For バ, imagine the old woman humming a soft 'baa' sound like a gentle sheep: baa -> バ, and she rocks the baby like a wet nurse.
