Nanny Needed - Now Hiring

I am a first time parent that will be returning to work at the end of October. My son will be about 3 months at that time. We need a in house sitter/nanny for max 3 days a week- MWF (my schedule varies). Max time per day would be 7AM-6:30 p.m. but my schedule varies a lot per day so time can change but you would know ahead of time. I want someone that will hold him and interact with him most of the day, except naps of course. Looking for someone with reliable infant/newborn experience. CPR and first aid certified. I do have 2 cats at home that are very friendly.
