When can a baby start daycare?

The short answer

• The law: Texas, California and Pennsylvania set no minimum age for daycare; their rules count a baby as an infant from birth. Maryland and Oregon don’t let centers care for babies under 6 weeks, and Minnesota’s center rules define infants as 6 weeks and older.
• Centers: many start at 6 weeks, and some take younger babies: in Pennsylvania, 1,586 of the 2,642 centers that post an infant price also post one for newborns under 6 weeks. Ask each center its youngest age.
• In practice: leave usually sets the date. Employed U.S. mothers take about 7.2 weeks off on average, and the federal FMLA guarantees up to 12 unpaid weeks to workers who qualify, so many babies start between 6 and 12 weeks.
• Medically: the American Academy of Pediatrics and the CDC don’t set a minimum age for daycare. The AAP recommends at least 12 weeks of paid leave for parents of newborns, and the main concerns in the first months are infections before the 2-month shots and fever: a baby 3 months or younger with a rectal temperature of 100.4°F or higher needs a call to the pediatrician right away.

The youngest age a daycare can take a baby, by state

Texas, California and Pennsylvania leave the youngest age to each center; Maryland and Oregon set 6 weeks, and Minnesota’s center rules start infancy at 6 weeks. For any other state, check its child care licensing rules; the license lookup for every state links each agency.

How many babies one caregiver may look after

Texas §746.1601 (ratios) and §746.1609 (group sizes); California §101416.5; Pennsylvania §3270.51; Childcare.gov. California family child care homes (§102416.5): a small home may care for 4 infants, or 6 children with no more than 3 infants; a large home, 12 children with no more than 4 infants. All three states allow more babies per caregiver than the national recommendation. What else to look for →

How many daycares take babies

• 6,717 of the 9,614 licensed child care centers in Texas (70%) are licensed to care for infants, and so are 1,377 of 1,589 licensed child-care homes and 1,443 of 1,743 registered homes. Being licensed for infants doesn’t mean a center takes 6-week-olds, so ask each one its youngest age.
• California licenses care for babies separately: there are 1,979 licensed infant centers, plus 1,555 centers with a single license that can cover several age groups, which may or may not include infants.
• In Pennsylvania, 1,586 centers post a price for newborns under 6 weeks (60% of the 2,642 that post an infant price), and every one charges the same as for older infants. A posted price isn’t proof a center enrolls newborns, so ask.

Infant rooms are small, because of the ratios above, so spots for babies fill first. If the centers near you won’t take a baby as young as yours, look at licensed home daycares (most take infants), a nanny or nanny share, a relative, or Early Head Start, which serves eligible families from pregnancy to age 3. Each center’s page shows its license and inspection record: Texas · California · Pennsylvania.

Texas: Health and Human Services licensing data (ages each operation is licensed to serve). California: Community Care Licensing (license type). Pennsylvania: COMPASS provider search (age groups and posted daily rates).

Vaccines: what a baby has had by each age

A baby who hasn’t had the 2-month shots can still start daycare: none of the three states requires a vaccine before 2 months. At 6 weeks, most babies have had only the hepatitis B vaccine and maybe an RSV antibody.

CDC child schedule and notes; Texas DSHS, 2026–27 child care requirements; California CDPH, child care immunizations; 28 Pa. Code §27.77. In March 2026 a federal court paused the January 2026 schedule and the 2025 votes of HHS’s new vaccine advisory committee, including its hepatitis B birth-dose change, so CDC again posts its July 2025 schedule; the government’s appeal was still undecided in mid-October 2026. The American Academy of Pediatrics publishes its own schedule. Follow your pediatrician’s advice. (Immunize.org; Courthouse News; AAP schedule).

Germs and a young baby’s health

• Babies aren’t born with a fully working immune system; antibodies from their mother protect them in the first months (AAP).
• Most children have 8 to 10 colds in their first two years, and children in child care may have more (AAP).
• A baby 3 months or younger with a rectal temperature of 100.4°F or higher needs a call to the pediatrician right away (AAP), so plan who can leave work when the center calls.
• Children who start nursery around age 1 catch more infections from ages 1 to 5, and the pattern reverses once they start school (UCL and Cambridge review, 2026).

Is there a best age to start daycare?

No age is best for every baby. The most comprehensive U.S. study of early child care (NICHD, children born in 1991) found that family factors were stronger and more consistent predictors of how children did than any aspect of child care. Higher-quality care went with somewhat better language and thinking skills, though the link was not a strong one, and 30 or more hours a week went with somewhat more behavior problems at age 4 and in kindergarten, as reported by caregivers.

Little research looks at babies as young as 6 to 12 weeks. In Norway, where children rarely start before 9 months, starting earlier predicted modestly more aggression at age 2 that faded to negligible by 4 (2015 study). After Quebec made child care cheap for children under 5, the cohorts with more access had worse behavior into the school years and worse health and more crime later; that study measured access to care, not start age (2019 study). The American Academy of Pediatrics recommends that parents of newborns have at least 12 weeks of paid leave (AAP). What you can control is the quality of care and the hours: a caregiver who responds to your baby, a small group and a clean inspection record.

How parental leave sets the start date

• Federal law (FMLA): up to 12 weeks of unpaid, job-protected leave, if you’ve worked 12 months and 1,250 hours for an employer with at least 50 employees within 75 miles (Department of Labor). About 56% of workers qualify (Labor Department surveys, 2018).
• California: state disability pays for up to 6 weeks after a birth (8 after a C-section), then Paid Family Leave pays about 70% to 90% of wages for up to 8 weeks (at most $1,765 a week in 2026): about 14 paid weeks after a birth (16 after a C-section), plus up to 4 weeks before the due date (EDD, EDD).
• Texas and Pennsylvania: no state paid leave program; paid leave depends on your employer. California is one of 14 states, plus D.C., with a paid family leave law, though some states’ benefits haven’t started yet (Bipartisan Policy Center tracker, September 2026; Child Trends).
• What mothers take: employed mothers take about 7.2 weeks on average (9.4 in states with paid leave, 6.9 elsewhere); about a quarter keep working in the two weeks right after the birth, and more than half are back by week 10 (Minneapolis Fed, 2026).

When to start looking for daycare

1. As soon as you’re pregnant: list your options

   Spots for babies are the hardest to find: in the 19 states and D.C. the Center for American Progress studied, licensed care had room for just 23% of infants and toddlers, and spots were more than three times as scarce as for 3- to 5-year-olds (CAP, 2020). Price centers and home daycares, and check whether you qualify for help paying: Texas, Pennsylvania’s Child Care Works, or your state’s program.

2. By about 20 weeks: tour and join waitlists

   Nebraska’s quality-rating program suggests starting the search as early as 20 weeks into a pregnancy (Step Up to Quality). Join more than one list, and ask your place on it and whether you’d have to start paying if a spot opens before your leave ends. By 2018, nonrefundable waitlist fees, such as $50 to $200 at Seattle-area centers, were becoming routine in the most expensive U.S. cities (AP); Colorado now requires providers to refund fees paid since Jan. 1, 2026 (minus a small administrative charge) if no spot is offered within six months and the parent asks in writing (The 74).

3. Third trimester: check records and hold a spot

   Read each center’s inspection record, ask about its infant ratio, safe sleep, feeding plan and sick policy, then pay the deposit and get the enrollment forms. In a 2026 survey, 52% of parents who pay for child care searched for two months or more (Care.com).

4. A month before: paperwork and practice

   Get the health form signed at a checkup, bring the immunization record, write the feeding plan, practice bottle feeding and label everything. What to pack, by age →

5. The first weeks: start slowly

   Many centers suggest shorter days at first. Expect the first colds, and line up backup care for sick days.

What to check in an infant room

• Caregivers and group size: No more than 4 babies per caregiver in Texas, California and Pennsylvania centers (3 is the national recommendation), in a small group. Count them when you visit.
• Safe sleep: Babies sleep on their backs in their own crib with nothing else in it. Texas requires a face-up position in the infant’s own crib (§746.2427). Safe sleep rules and violations →
• Feeding: A written feeding plan, how breast milk is stored and labeled, and bottles that are held, never propped (Texas requires written feeding instructions, §746.2421, and bans propped bottles, §746.2419). California centers must have a feeding plan, including breast milk or the kind of formula, before a baby’s first day (§101427).
• Diapering and handwashing: A diaper area away from food, and caregivers who wash their hands after every change.
• Sick policy: When a baby with a fever must go home and how soon you’ll be called. Sick-day rules →
• The inspection record: Read the center’s citations before you sign: Texas · California · Pennsylvania · other states.

Do daycares charge more for newborns?

Care for babies costs more than for any other age, because each caregiver looks after so few children. In Pennsylvania, of the 1,586 centers that post both a newborn and an infant rate, every one charges the same for both. Infant daycare cost by state and county →
