Balance - Is it possible?

Tonight, my son said to me, "Momma, sometimes I wanna spend some time with you." I thought about it, and lately, we haven't been spending much time together at all. I got a new job in August with a late shift that pays better than most jobs available for a person without a degree (hell, even some that do require a degree). The thing is, most nights when I pick him up, it's time for him to go bed. So how does this work? This continually proves my and conscious society's theory that child rearing is not for one person, but for two. But until I'm in that place, how am I supposed to handle this? I love my baby, and I work my ass off for him. But at what expense? If his dad lives out-of-state and his mom lives at work, who lives with him????
