Working overnights while pregnant..

Brandy
I work overnights as a CNA and take care of my 2 year old daughter during the day so we don't have to put her in daycare. We are currently trying for #2. I get 4-5 hours of sleep on a good day. Any suggestions from any of you that have worked nights? Just wondering if I'm gonna crash and burn or put the baby at risk when pregnant.
