Nanny Needed

Looking for a nanny for my son starting in January, he will be 5 months. I am a nurse who works day/night shift 7-7. When I work day shift, I would need someone 6a-6p until my boyfriend gets home. When I work night shift, I would need someone at 5:15 a.m. while he leaves for work and the end time would depend if I just need to nap after work, or if Im working again that night. Would be 1-3x week depending on days I work/wouldnt need help on the weekends.
