What species the mother is plays a huge role in the answer to that question.
If it's a succubus, and she so happens to allow herself to get pregnant, then her child will be born as a soul that 'splits' from her own, much like how a slime divides. Ergo, the 'child' will be fully grown and her appearance will range from looking exactly like her mother, or nothing like her mother.
But, for example, if it's suika's child, she can feed her offspring as any human mother would, by breastfeeding her. Except instead of nutrient rich milk, she'll be feeding her own energy to her child.
