Starting Daycare at 6-12 Weeks

The earliest option, driven by necessity.

Why Families Choose This Age

Practical reasons:

• Parental leave ends (US average: 10-12 weeks)
• No paid leave available
• Financial necessity
• Job requirements

The reality:

• Many parents don't have a choice
• US lacks mandated paid leave
• Infant care is available and safe

What to Expect

Baby's experience:

• Babies this young adapt easily to routines
• Haven't developed stranger anxiety yet
• Sleep patterns still developing
• Feeding schedule is primary concern

Parent concerns:

• Emotional difficulty leaving young infant
• Breastfeeding logistics
• Communication with caregivers
• Trust building

Making It Work

Tips for success:

1. Choose a daycare with low infant ratios (1:3 or 1:4)
2. Visit multiple times before starting
3. Communicate feeding preferences clearly
4. Establish pumping routine if breastfeeding
5. Build relationship with primary caregiver

Breastfeeding support:

• Many daycares accommodate breast milk
• Provide labeled bottles daily
• Discuss warming preferences
• Some moms visit during lunch to nurse

Starting Daycare at 3-6 Months

A common transition point.

Why Families Choose This Age

Common reasons:

• Extended leave (some employers offer 3-6 months)
• FMLA protection ending (12 weeks)
• Feeling ready to return to work
• Infant gaining more predictable schedule

Developmental Considerations

At 3-6 months, babies:

• Have more predictable sleep cycles
• Can hold head up, may be rolling
• Starting to smile and engage socially
• Developing attachment but not stranger anxiety

Advantages:

• Baby more interactive and engaging
• Caregivers can bond easily
• Still before stranger anxiety develops
• More established feeding routine

What to Expect

Transition typically smooth because:

• Baby still very adaptable
• Not yet in separation anxiety phase
• Enjoys new faces and stimulation
• Routines transfer well

Challenges:

• May experience sleep disruption initially
• Illness exposure begins
• Pumping/bottle transition if breastfeeding

---

Starting Daycare at 6-12 Months

The separation anxiety window.

Why This Can Be Harder

Developmental reality:

• Separation anxiety typically peaks around 8-10 months
• Baby recognizes primary caregivers
• Stranger wariness is normal and healthy
• Object permanence developing

What parents experience:

• More crying at drop-off
• Clingier behavior
• Possible sleep regression
• Longer adjustment period

Making It Work

Strategies for success:

1. Gradual transition (if possible)
2. Consistent drop-off routine
3. Quick goodbyes (don't prolong)
4. Comfort object from home
5. Same caregiver consistency

Sample transition schedule: | Day | Duration | Notes | |-----|----------|-------| | 1-2 | 1-2 hours | Parent stays nearby | | 3-4 | 2-3 hours | Parent leaves but nearby | | 5-6 | Half day | Morning only | | 7-8 | Extended day | Building to full day | | Week 2 | Full days | Monitor adjustment |

The Silver Lining

Benefits at this age:

• Baby mobile and curious
• Enjoys exploration
• Benefits from stimulation

Why Families Choose This Age

Common reasons:

• Parent returning to work after extended leave
• Child needs peer interaction

• Can communicate needs

Making the Transition

Strategies:

2. Read books about daycare - Normalize the experience

Starting Daycare at 3-4 Years

Preschool readiness.

Why This Often Works Well

Developmental advantages:

• Ready for structured learning
• Interested in peers and friendships
• Can communicate needs clearly
• Understands routines and schedules
• Often excited about "big kid" school

This Age Is Different

3-4 year olds:

• Benefit significantly from peer interaction
• Need socialization before kindergarten
• Ready for curriculum and learning activities
• Can handle longer separations
• Make real friendships

What to Look For

At this age, prioritize:

• Educational curriculum (pre-reading, math basics)
• Social-emotional learning
• Kindergarten readiness activities
• Appropriate peer groupings
• Teacher qualifications

Common Concerns

"Is 3-4 too late?" No. Many children start group care at this age and thrive.

"Will they be behind?" Research shows children catch up quickly and often excel.

"Will they have trouble making friends?" Children at this age are naturally social and make friends easily.

What Research Says

The science on daycare timing.

Key Research Findings

NICHD Study (longitudinal research):

• Quality of care matters more than quantity or timing
• High-quality daycare doesn't harm attachment
• Can improve cognitive and language development
• Social benefits especially strong for children from disadvantaged backgrounds

What "quality" means:

• Low child-to-caregiver ratios
• Consistent, responsive caregivers
• Stimulating environment
• Age-appropriate activities
• Caregiver training and education

Attachment Research

Attachment develops through:

• Consistent, responsive parenting at home
• Not damaged by quality daycare
• Multiple secure attachments are healthy
• Quality of interactions matters most

Important nuance:

• Very long hours (50+/week) in low-quality care shows some negative effects
• Moderate hours in high-quality care shows neutral or positive effects
• Parent-child relationship remains primary

Socialization Research

Children in group care:

• Often have stronger social skills
• Learn sharing and cooperation earlier
• May have larger vocabulary (exposure to more language)
• Better prepared for school settings

Making the Decision

A framework for your family.

Questions to Ask Yourself

Practical considerations:

1. When does parental leave end?
2. What does your work schedule require?
3. What care options are available and affordable?
4. What are the waitlist timelines in your area?

Child-focused considerations:

3. What does your child seem to need right now?

Family considerations:

1. What does your family need to function well?

Making Transition Easier at Any Age

Universal Tips

1. Choose quality care - This matters more than timing
2. Build relationship with caregivers - Trust makes everything easier
3. Maintain consistent routine - Same goodbye, same pickup
4. Stay connected - Ask for updates, share information
5. Be patient - Adjustment takes time at any age
6. Take care of yourself - Parent guilt is normal but not helpful

Red Flags vs Normal Adjustment

Normal adjustment:

• Crying at drop-off that stops quickly
• Clinginess for first few weeks
• Some sleep disruption
• Changes in appetite
• Temporary behavioral changes

Seek help if:

• Crying continues all day for weeks
• Complete refusal to eat
• Regression that doesn't improve
• Signs of fear or trauma
