Best Job For Single Mum?

Currently still studying. And my family takes care of my LO since my boyfriend left us. In the day it’s just my maid and my grandma (90 years old) at home with my LO, in the evening when my parents are back they help me look after her, and I take care of her at night (including night feeds + study / finish my assignments ) it’s definitely not easy but we cannot afford for infant care since most of them are around $1.4-1.7K 😫
