When families in Boston start researching childcare, the first thing most of them do is compare the numbers. A full-time nanny looks expensive on paper. Daycare looks more manageable. And then reality sets in.
The cost comparison is only part of the story. For many Boston families, especially those with more than one child, non-traditional schedules, or high professional demands, the actual math looks very different from the headline number. Here is what the side-by-side chart typically leaves out.
The Numbers, First
Before getting into the nuances, it helps to understand what both options actually cost in 2026.
Daycare in Greater Boston: Center-based daycare for infants in Boston averages $2,200 to $2,900 per month, with downtown neighborhoods like Back Bay and Beacon Hill on the higher end. Toddler care typically runs $1,800 to $2,400 per month, and preschool-age care comes in closer to $1,400 to $2,000. Massachusetts consistently ranks as one of the most expensive states in the country for childcare, and Boston sits at the top of that list.
Full-time nanny in Greater Boston: In the Boston market, an experienced full-time nanny typically earns $32 to $40 or more per hour, depending on experience, qualifications, and job responsibilities. That translates to a gross annual salary in the range of $65,000 to $85,000 for a full-time position. When you factor in payroll taxes (roughly 8 to 10% of gross wages as the employer share), the total cost of employment increases accordingly. You will also want to budget for paid time off, guaranteed hours, and any benefits the position includes.
Those are the headline numbers. Now here is what they do not tell you.
The Waitlist Problem No One Wants to Talk About
The biggest hidden cost in Boston daycare is not money. It is time.
In Boston, infant waitlists at quality licensed centers typically run anywhere from 6 to 18 months. In high-demand neighborhoods and at sought-after programs, 12 to 24 months is not uncommon. Many families join waitlists before their child is born, and some before a pregnancy is even announced.
What that means in practice: if you have a baby and have not already secured a spot, you may be looking at a gap of a year or more before a daycare opening becomes available. In the meantime, families cobble together coverage, often at significant cost and stress.
A nanny can start when you need her to. That flexibility has real value, even if it does not show up in a monthly cost comparison.
Hidden Costs on the Daycare Side
The monthly tuition figure is just the beginning. Most Boston families encounter several additional costs that are rarely discussed upfront.
Backup care. Daycare centers operate on fixed hours and close on holidays, weather days, and occasionally for staffing issues. When your center closes unexpectedly, you need a plan. For many families, that means last-minute babysitters, a family member stepping in, or a parent taking a day off work. None of those options are free.
Sick day policies. Most licensed centers will not accept sick children, and many require a waiting period after fever or illness before a child can return. Repeated absences can mean significant disruption, especially for families without flexible work arrangements.
Activity, supply, and enrichment fees. Tuition is rarely all-inclusive. Many programs charge separately for field trips, curriculum materials, and extracurriculars. These line items add up over the course of a year.
Registration and deposit fees. Securing a spot often requires a non-refundable deposit and annual registration fee, sometimes paid a year or more in advance.
Hidden Costs on the Nanny Side
Transparency matters here, too. Hiring a nanny is a genuine employment relationship, and families who do not understand the full cost can find themselves surprised.
Payroll taxes. As a household employer, you are responsible for withholding and remitting the nanny’s share of Social Security and Medicare, and paying your own employer share, which typically runs 8 to 10% above gross wages. Using a payroll service simplifies this considerably. We often refer families to GTM Payroll as a trusted resource.
Guaranteed hours. Most nanny agreements include a guaranteed hours provision. This means that if you cancel a workday, the nanny is still paid for those hours. This is standard and appropriate, but it is an important factor to include in your budgeting. For more on how guaranteed hours work, see our dedicated post on the subject.
Time off and benefits. Paid vacation, sick days, and holidays are typical. You may also provide a health insurance stipend or a professional development contribution depending on the role.
Agency placement fee. Working with a placement agency like The Washburn Agency involves a one-time fee for the search and placement process. What you receive in return is a fully vetted, interview-ready candidate, reference checks conducted directly and thoroughly, and support through the offer and onboarding process.

The Break-Even Point: Two or More Children
Here is where the cost comparison often shifts decisively in the nanny’s favor.
If you have two children in full-time daycare in Boston, you are looking at combined tuition of $3,500 to $5,500 per month, often more. A second child in daycare means a second full tuition. A nanny caring for two children typically earns a modest bump in pay, not double the rate. For families with two young children, that difference alone can close much of the gap between the two options.
Families with a newborn and a toddler often find the math works clearly in the nanny’s direction. Two infant or toddler daycare slots in Boston can easily exceed what it costs to employ a full-time, experienced nanny, and the family retains the benefits of individualized, in-home care.
Schedules That Daycare Simply Cannot Accommodate
Daycare operates on daycare hours. For many Boston families, that is not the schedule they actually live.
Hybrid and remote workers often need coverage that starts early or extends into the evening. A nanny’s schedule is set by the family, not by a center’s operating hours.
Frequent travelers need care that can flex. A nanny who travels with the family or adjusts her schedule week to week is simply not something a licensed center can offer.
Families with irregular or non-traditional hours, including medical professionals, executives, and entrepreneurs, routinely find that no daycare program matches how they actually work. A nanny or family assistant can be structured around the household’s real needs.
Families expecting a second child often find the logistics of two daycare drop-offs and pickups, with two different policies and two different sick day windows, more disruptive than anticipated.
When Daycare Does Close Unexpectedly
It happens. Snow days, staffing shortages, illness outbreaks, flooding, and unexpected maintenance can close a center on short notice. Most families are not prepared for how often this occurs or how disruptive it is.
With a full-time nanny, your care does not depend on a center remaining open and fully staffed. That predictability, particularly for parents in demanding professional roles, is worth more than most families account for in advance.
Which Option Is Right for Your Family?
The honest answer is that it depends. Daycare is a genuinely good option for many families, particularly those with older toddlers and preschool-age children who thrive in a structured group setting, flexible work arrangements, and access to a high-quality program near home.
A full-time nanny tends to be the stronger fit when:
- Your child is an infant or very young toddler
- You have two or more children at home
- Your schedule does not conform to traditional daycare hours
- You travel frequently or have unpredictable work demands
- Consistency of caregiver matters deeply to your family
- You value the flexibility of in-home care and individualized attention
