Nanny Needed

I am looking for a great baby sitter for 1 child in Lithia Springs. We would prefer a sitter who has their own car and who does not smoke. I am a Registerered nurse and I work 12 hr shifts (7am-7pm) 3 days a week. Must be flexible because I do not work the same 3 days a week but I am willing to schedule myself regularly to fit sitters schedule as well. My son is in KK and would need to be dropped off to school at 7 a.m. and picked up by 2:10 p.m. Before and after care is needed. He is potty trained, walks, and can verbalize his needs. On weekends it would be a full day (6am-8pm).
