Holiday leave for maternity leave

Bowser • 🌈🌈 due March 2016
I got a job offer over the weekend. It is part time, collecting children after school and minding them until the parents come home.
Now I did tell her I was pregnant and would have to finish up the middle to the end of February as I am due the 1st of March.
But she suggested I work up until I give birth( which that I don't mind doing) but she then wants my maternity leave to be 2 weeks basically 2 weeks holiday leave!
Her explanation was that women done this for years having children one after the other. It's minding children so I would be treating them like my own. She done a very good job at trying to persuade me.
But I just don't know. 2 weeks is a very little time. I struggled breastfeeding my son, to the point where he was always on my boob at the beginning, so of course formula came up. 
Do you think I should try see how it goes or just work up until I am pregnant then quit?
Or has anyone gone back to work that soon?
