Just 2, you and your mum because you are only sponsoring your mother.

thx for your advice
if in the future after i sponsor my mum, i want to sponsor my father, then the family size would be 5 (me and mum and father and his spouse and son),right ? do have have to include my fathers spouse in the undertaking?

Yes. It will be 5 at that point.
