Part-time nanny for active 9-month old

Sittercity hiring for Part-time nanny for active 9-month old jobs in Brooklyn, NY, US

We're a bi-lingual couple (Portuguese/English) who love spending time with our baby in between work calls. My husband and I work flexibly (I am a writer, he's in sales) and are often at home caring for our baby, but our schedule is often packed with meetings (especially in the mornings).
Someone to care for our baby mostly in the mornings and daytime, but we are flexible to other part-time arrangements. We want help with basic needs, including bottle feeding, solids introduction, putting him on naps, and actively playing with him (ideally with activities that help his development). Also someone whose priority will be his safety and wellbeing, 100% present while at work. Very light housekeeping (washing bottles, cleaning his feeding chair) are also wanted.
