Childcare Needed - Full-time / Part-time

Im a nurse. My schedule is different. I work Monday Tuesday Friday 7:30a-7:30p Saturday Sunday 8a-5p one week and the next week I work Wednesday Thursday 7:30a-7:30p. So five days one week and two days the next week. Im still pregnant right now so I might end up changing my mind and doing only prn and would only need assistance a few days a month. Right now I dont have specific care I feel like I will be able to figure that out with the person who will be taking care of him when Im at work when that time comes!
