Starting daycare with a baby: how to prepare, what to expect and reduce separation anxiety

Q: What age should a baby start daycare?

There is no universally ideal age — the right time depends on family circumstances, parental leave entitlement and the quality of available care. From a developmental standpoint, the AAP notes that infants under 12 months in low-quality childcare may show elevated cortisol levels. High-quality care with responsive caregivers, low child-to-staff ratios and consistent routines is appropriate from around 3–4 months. Many families start between 3–12 months based on return-to-work timing.

Q: How long does the daycare adjustment period take?

Most babies take 2–6 weeks to fully adjust to daycare. The first week is typically the hardest, with peak separation distress at drop-off. By week 3–4, most babies are settling more quickly and forming bonds with their key carers. Some babies (particularly those starting between 9–18 months — the peak of separation anxiety development) may take longer. Full adjustment, where the baby greets the setting happily, usually happens within 6–8 weeks.

Q: My baby keeps getting sick at daycare — is this normal?

Yes, frequent illness in the first year of daycare attendance is entirely normal and represents the immune system building its defences. Children in group childcare get an average of 8–12 colds per year in their first year, compared to 4–6 for home-reared children. This immune-building phase means fewer illnesses in subsequent years and typically less illness during school years. Ensure the setting follows proper handwashing and exclusion policies for genuinely infectious illnesses.

Q: What are my rights for pumping breast milk at work?

In the United States, the PUMP Act (2022) requires most employers to provide reasonable break time and a private, non-bathroom space for expressing breast milk for up to one year after the baby's birth — regardless of whether the employee is exempt or non-exempt. Many other countries have similar protections. Contact your HR department before returning to work to establish a pumping plan, including frequency, duration and location of sessions.

The daycare transition is one of the most emotionally charged milestones of the first year — for parents at least as much as for babies. Here is how to make it as smooth as possible.

What age is right for starting daycare?

Families start daycare at different ages depending on parental leave entitlement, financial circumstances and personal preference. From a developmental standpoint, the American Academy of Pediatrics (AAP) notes that infants under 12 months in low-quality childcare environments can show elevated cortisol levels — a stress indicator. The key word is quality. High-quality daycare with a warm, responsive lead carer, a low child-to-staff ratio (1:3 or better for infants), and a consistent routine is appropriate from 3–4 months.

The most challenging ages for separation anxiety are 8–18 months, when object permanence has developed enough for a baby to understand that you have left, but not yet matured enough to understand that you will return. Starting daycare at 3–6 months — before this window peaks — or after 18 months can ease the transition for some families.

Settling-in visits: invest time upfront

Most good daycare settings offer a settling-in programme — a series of short visits where you stay with your baby in the new environment before leaving them alone. This is not optional time for busy parents to skip; it is the most effective investment in a smooth transition.

A typical settling-in schedule over 2 weeks:

Visit 1 (1 hour): You stay the whole time. Baby explores with you as a safe base.
Visit 2 (1–2 hours): You stay but step back — let the key carer take the lead in interaction.
Visit 3 (1–2 hours): Leave for 20–30 minutes. Return before distress peaks.
Visit 4–5: Gradually extend the away time. Full mornings, then full days.

The goal is for your baby to form a bond with their assigned key carer before you disappear fully. A baby who is fond of their carer settles far more quickly at drop-off than one who does not yet recognise that person as safe.

Transition objects and comfort items

A transition object — sometimes called a comfort object or lovey — is something that carries your scent and provides familiarity in an unfamiliar environment. Options that work well for daycare:

A small muslin square that you have slept with for a night, so it carries your scent.
A small soft toy that lives in the nappy bag and goes to daycare each day.
A family photo laminated and kept in the baby's cot cubby (some settings do this for toddlers).

Check your daycare's policy on comfort objects — most infant rooms permit them, but some have restrictions on soft toys for safe sleep environments.

The drop-off routine: quick, consistent and positive

Drop-off is the moment most parents dread. The evidence on what works is clear: a brief, warm, consistent routine — then leave.

Do the same short routine every day: kiss, specific phrase ("I love you, I'll be back after your afternoon nap"), handover to carer.
Do not sneak out. Sneaking out feels kinder but actually increases anxiety because the baby cannot learn to predict your departure. They trust you less at subsequent drop-offs.
Do not linger. Prolonged goodbyes amplify distress. Your anxiety communicates to your baby that there is something to be anxious about.
Once you leave, call the setting after 15–20 minutes if you are worried. In almost all cases, babies settle within minutes of the parent leaving — it is the moment of separation that is hard, not the state of being there.

Illness at daycare: building immunity

Expect your baby to be sick more frequently in the first year of daycare than they were at home. This is not a sign that daycare is bad for your baby — it is the immune system doing exactly what it is designed to do. Children in group care in the first year get an average of 8–12 respiratory illnesses compared to 4–6 for home-reared children.

Essential backup plan components:

Identify 2–3 people who can collect a sick baby on short notice (partner, grandparent, trusted friend).
Know your employer's sick-child leave policy before you need it, not during a crisis.
Keep a paediatric sick-day kit stocked: thermometer, infant paracetamol, saline nasal drops, a spare set of everything your baby needs.
Know your daycare's exclusion criteria in advance — most settings require 24–48 hours symptom-free after fever, vomiting or diarrhoea before return.

Pumping at work: planning your schedule

If you are breastfeeding, returning to work requires coordinating pumping sessions at work with daycare feeds. A workable framework:

In the US, the PUMP Act (2022) entitles most employees to reasonable breaks and a private, non-bathroom pumping space for up to 1 year post-birth.
Pump at work at roughly the same intervals your baby feeds. For most babies under 6 months, this means every 2.5–3 hours — typically once mid-morning and once mid-afternoon for an 8-hour workday.
Build your freezer stash 2–4 weeks before returning to work by adding one extra pumping session per day (usually after the morning feed, when supply is highest).
Send enough milk to daycare for one extra feed as a buffer — bottles take longer for daycare staff to prepare than a direct feed takes you at home.
Brief your daycare on paced bottle feeding to reduce overfeeding and protect your supply.
