I have trouble waking up to sounds, what should I do? - trouble waking up

Well, recently, a parent, and now after 2 months, my girlfriend finally working again. I work 3 shifts (11-7) and the working day (8a-5p training and usually 12.15-8.45 p), the problem I have is that I have trouble waking sound of our son. We spent two days woke up in practice and when he cried to be fed, not stirred. Now I'm petrified and tried to sleep while she works, but when, during sleep at home really more time together. To try all tips, nap, when my son to sleep and wake up when it easier to cry?
