Busy Banker: Can I ask my Sister To Breastfeed My Baby?

I am really worried about the condition of things. I am an avid reader of this blog and i hope I’d be able to get advice to my problem.

I am a banker with a new generation bank in Lagos. I conceived last year and put to bed 7 months later making my baby a premature. I was giving 2 months of maternity leave by my employer but my problem is that i can not breastfeed my baby due to work stress.
