Infant Care or Helper?

Husband and i are not on the same page in regards to this. I've done my research and it stresses me out. We argue almost everyday till there's no full stop. In-laws are out of the picture. Infant care; exposure to sickness is high within other babies. Helper; afraid of her dishonesty in taking care of my baby. #advicepls mummies. Really need alot of advice and moral support.
