Multiple Entry Visit Visa

[Sweetiepie]

Hi,

I'm pregnant and would like to bring my parents during delivery.
I'm due by January end. My mother is currently working and retiring by end of february.

I would like them to come here by beginning of december and leave by February end. Can my mom come back again by March, Once her formalities at office is done?

Is this allowed? Or does she require to reapply? Will she be granted entry again?

Please let me know.
