For your daughter, I’d put **warm, responsive caregivers, safe routines, and consistent staffing** at the top of the list. A good infant program should give her plenty of individual attention and caregivers who learn her cues.

**About the ratios:** legal limits depend on your country or state, and meeting those limits doesn’t by itself establish quality. As reference points:

- **1 adult to 4 infants** matches ZERO TO THREE’s recommendation for children under three, with a maximum group size of eight. The American Academy of Pediatrics recommends a stricter **1:3 for babies under 12 months**.
- **1:12 for ages 3–5** means substantially less adult attention than the AAP recommends: **1:7 for three-year-olds and 1:8 for four- and five-year-olds**.

These are quality recommendations, not a determination of what’s legal where you live. Ask about **total room size and coverage during breaks or staff absences**, too. [ZERO TO THREE](https://www.zerotothree.org/wp-content/uploads/2025/02/ratios_brief-1.pdf), [AAP guidance](https://www.healthychildren.org/English/family-life/work-and-child-care/Pages/choosing-a-child-care-center.aspx)

Here’s a checklist your wife can take along:

| What to check | What to observe or ask |
|---|---|
| **Caregiver interactions** | Do adults respond to crying, comfort children, make eye contact, and talk with them? Watch what happens when several children need help at once. |
| **Consistent caregivers** | “Who would be our daughter’s main caregiver? How long have the infant staff worked here? How often do children change rooms or caregivers?” |
| **Actual staffing** | Count children and caregivers actively supervising them. “Who covers lunch breaks, diaper changes, and sick days? Do you combine rooms at opening or closing?” |
| **Training** | Ask about infant-care experience, ongoing training, background checks, and current infant/child CPR and first-aid certification. |
| **Communication** | Will you receive information about feeds, naps, diapers, and concerns? Can staff explain how they would help your daughter settle in? |
| **Discipline** | Ask how they handle crying, biting, and tantrums. Look for patient comfort and guidance; shouting, humiliation, or rough handling are serious concerns. |

These checks reflect the emphasis on relationships, staffing, training, and parent communication in [ChildCare.gov’s guidance](https://childcare.gov/consumer-education/find-and-choose-quality-child-care) and the [AAP’s child-care selection advice](https://www.healthychildren.org/English/family-life/work-and-child-care/Pages/making-child-care-choices-count-for-your-family.aspx).

For the **infant room**, also check these specifics:

- **Sleep:** Babies should be placed on their backs on a firm, flat sleep surface, with only a fitted sheet—no pillows, loose blankets, bumpers, or toys. Swings and car seats should not serve as routine sleep spaces. [AAP safe-sleep guidance](https://www.healthychildren.org/English/ages-stages/baby/sleep/pages/a-parents-guide-to-safe-sleep.aspx?form=HealthyChildren)
- **Feeding:** Ask whether staff follow individual feeding cues, support breast milk if needed, hold babies for bottle feeds, and record intake. Bottles should never be propped. Ask how allergies and choking emergencies are handled. [AAP feeding checklist](https://www.healthychildren.org/English/family-life/work-and-child-care/Pages/your-child-care-checklist.aspx?form=HealthyChildren)
- **Daily experience:** Look for talking, singing, books, and supervised floor play. Ask how they accommodate each baby’s sleep and feeding routine.
- **Hygiene and safety:** Observe handwashing and diaper-changing practices. Check secure entrances, authorized pickup procedures, and whether hazards are out of reach. Request written illness, medication, and emergency policies.

Before enrolling, **check the license, inspection reports, and substantiated complaints with the relevant local regulator**. Ask for references from families currently using the infant room. In the U.S., [ChildCare.gov explains how to find those records](https://www.childcare.gov/consumer-education/find-and-choose-quality-child-care/simple-steps-for-finding-and-choosing-child-care).

The Mommy and Me class is a useful first look. I’d also arrange to observe the **ordinary infant-care day with the staff who would actually care for your daughter**: the class may have different staffing and doesn’t show how feeding, naps, and competing needs are managed. A particularly revealing question is: **“What happens when one baby needs feeding, another needs changing, and another is crying?”**
