My Guy's crazy work schedule

Jessica
My guy and I have been together for three years, and have been trying to conceive for about six months. 
He does warehouse work, and he's always had day shift jobs, which really went well with my work schedule. Recently, he got a new job from 6 pm, to anywhere from 3 am to 6 am. It pays a hell of a lot more, but it really put a strain on us trying to have a little one of our own.
He was married before and he already has a ten year old boy who doesn't live with us, and up until this year, believed he had a daughter with his ex, but she had been lying to him for six years, but that's a different story... So, I feel like I want to give us a child to truthfully raise together, so he can be the full time amazing father he is. 
I just want to know if there are any other ladies out there that have the same issue I'm having, or have any useful advice for me, because it's really driving me insane. Can anybody help me?
