Childcare in NYC is expensive. Here a rundown of the different types of care available for fulltime, working parents.
Daycare- Usually a more school like environment, classes are broken down by age.
Home/family daycare- Usually mixed age, hosted in a hoe or apartment.
In general Home daycares are cheaper. i have heard of families paying $800 a month for home daycare up to over $3000 a month for a school daycare setting. Midtown, UES and UWS seem to be the priciest areas for Daycare options. Read here for more information- https://www1.nyc.gov/site/doh/providers/health-topics/children-and-adolescents-childcare.page

Nanny- A nanny comes to your home and watches your child, you set the day/time/hours with the nanny. Nannys can be found by parent referrals as well as agencies.
Nanny Share- 2 (or more) families share a nanny. Nanny usually alternates by week who hosts the children.
Au Pair- Usually live in- comes from another country to live and care for your child. Set up by an agency due to visa requirements.
Prices vary for nanny care- I have heard of parents paying nannies $10 an hour up to $25 an hour. SOme families choose off the books, where other choose to pay taxes on the nanny.
