CDA Birth to Five common mistakes

CDA Birth to Five · Understand the traps and how to avoid them.

Mistake 1

On a safe-sleep item, marks 'place the infant on the stomach or side' or 'keep a soft blanket or stuffed animal in the crib' as the correct practice.

The candidate is repeating advice from family or personal experience, or fears the infant will choke or get cold, and has not updated to current safe-sleep guidance.

What to do instead

Apply the ABC rule every time: Alone, on the Back, in a Crib. Use a firm mattress and fitted sheet, keep loose bedding, pillows, bumpers, and toys out, and offer a pacifier at nap if the program allows.

Mistake 2

In a scenario with patterned bruises or a child's disclosure, chooses 'ask the family what happened and decide whether to report' or 'wait until there is more proof' instead of reporting.

The candidate fears being wrong, feels loyal to the family, or believes a caregiver must investigate before reporting.

What to do instead

Use the reasonable-suspicion standard: report to the designated child protective agency or supervisor per policy, do not investigate or confront, document objective observations, and keep the report confidential.

Mistake 3

Approves a plan where one teacher steps into another room for supplies while a small group stays in the play area, or stands where shelving blocks the view of children.

Staffing pressure and familiarity make the candidate underestimate how quickly young children move into danger.

What to do instead

Maintain sight and sound supervision at all times: count children, position yourself to scan the whole space, take children with you, and use a buddy or call for relief rather than leaving the group.

Mistake 4

Selects a teacher-led worksheet, flashcard drill, or product-focused craft as the best activity for 4-year-olds because it looks like school readiness.

The candidate equates learning with direct instruction and feels pressure from families or elementary schools to show academic output.

What to do instead

Choose play-based, hands-on, child-initiated experiences: open-ended materials, sensory play, storybook talk, and process art. Explain to families how play builds language, math, and self-regulation.

Mistake 5

For a child with an IFSP or IEP, chooses to have the child do the same activity as everyone else without modification or to wait for the specialist to address goals.

The candidate confuses inclusion with identical treatment and believes specialized goals belong only to therapists.

What to do instead

Adapt the materials, time, space, or response mode so the child can participate, embed IFSP outcomes in daily routines, and collaborate with the specialist and family rather than waiting.

Mistake 6

Responds to biting by biting the child back, using hot sauce or soap, or imposing a long time-out.

The candidate is embarrassed, worried about injury, and reaches for a deterrent that stops the behavior immediately.

What to do instead

Shadow the child during high-risk times, comfort the bitten child first, teach 'teeth are not for biting' with a replacement behavior, offer teething chews, and never shame or punish physically.

Mistake 7

When a child cries, says 'You're okay, there's nothing to cry about' and quickly distracts the child with a toy.

The candidate is uncomfortable with distress and believes stopping the crying is the goal.

What to do instead

Name and validate the feeling, stay calm and close, and coach a coping strategy. Use that moment to build emotional vocabulary and co-regulation rather than dismissing the emotion.

Mistake 8

Tells a family 'You need to stop carrying him at home' or sends a one-way note about a concern without asking about the family's routines, culture, or preferences.

The candidate adopts an expert stance, feels time pressure, and assumes the program's way is the right way.

What to do instead

Use two-way communication: ask how things work at home, listen for cultural and practical context, share observations without blame, and set a shared goal together.

Mistake 9

Writes 'Child is autistic' or 'has ADHD' in an observation note and uses that label to plan activities.

The candidate confuses observation with screening and diagnosis and wants a quick explanation for behavior.

What to do instead

Record objective, observable behavior with time, setting, and frequency. Use screening tools only as the program allows, refer for evaluation through proper channels, and plan from the child's actual skills and needs.

Mistake 10

Discusses a child's enrollment, behavior, or family situation in the staff lounge, with friends, or on social media.

Informal staff culture and venting make confidentiality feel optional, and the candidate does not recognize identifying details.

What to do instead

Share information only on a need-to-know basis, avoid names and identifying details, redirect gossip, follow the program's confidentiality policy, and use supervision or a trusted colleague for support.
