Infant child care advice??

Danielle • Married my best friend on 4/11/2015. I have a son—rainbow baby born 2016, and trying to grow our little family💗💗💗
I make about $1600/month after taxes, health insurance, 401k, etc. I heard child care can be very expensive especially for an infant! I live in the Los Angeles area and looking for advice.
My husband will support us if need be but if I can work AND afford child care that would be preferred. 
I would be more than happy to spend all of my time with my growing little family 💗💗💗
