Toddlers need control; preschoolers need explanation. The toddler stage is
autonomy vs shame, the preschooler is initiative vs guilt β and almost every
answer follows from that.

Simple honest explanation; let them handle equipment
β The two answers that keep reappearing
Toddler tantrum β ignore the behavior, keep them safe. Attention reinforces it.
Toddler resisting care β offer two acceptable choices. Never an open question.
βDo you want the pink cup or the blue cup?β, not βWill you take your
medicine?β
Preschoolers think illness is punishment for being bad. Say plainly that it is nobody's fault.
π¨ The leading cause of death in toddlers
Unintentional injury β and it is preventable teaching:
Drowning β never leave alone near water, including buckets and baths
Poisoning β locked cupboards; toddlers explore by mouth
Falls β stair gates, window guards
Burns β pot handles turned in, water heater below 49Β°C
β Milestones you should recognize
15 months β walks alone, 3β5 words
2 years β runs, 2-word phrases, ~50% intelligible
3 years β tricycle, 3-word sentences, ~75% intelligible
4 years β hops, dresses self, ~100% intelligible
5 years β skips, ties laces, prints name
The rough rule: number of words per phrase roughly matches age in years at 2 and 3.
Erikson: autonomy vs shame/doubt (toddler), initiative vs guilt (preschool). Piaget preoperational spans both β magical thinking, animism, egocentrism, centration.
Play: parallel in toddlers, associative in preschoolers.
Toddler motor: independent steps ~15 mo, walks well 18 mo, runs and kicks a ball at 24 mo, jumps with both feet ~2.5 yr. Uses a spoon at 24 mo.
Language: ~50 words by 30 months, 2β3 word phrases at 2 years. Preschooler exceeds 2,100 words by 5β6, and normal dysfluency should not be corrected.

Screening calendar: anemia at 15 and 30 months; lead and autism at 18 and 24 months; vision starting at 3 years.
Lead above 5 mcg/dL is abnormal. Treatment is chelation.
Cow's milk capped at 16β24 oz/day because calcium blocks iron absorption. Whole milk until 2, then low-fat.
Physiologic anorexia β the toddler appetite drop β is expected, not pathology.

📕 From your ATI review book
Covered by ch. 4 (toddlers) · ch. 5 (preschoolers).
Toddler growth: about 5 lb (2.3 kg) and 2–3 in a year, reaching roughly half of adult height by age 3. Preschooler: about 4.5 lb (2 kg) and 3 in (7.6 cm) a year.
Language. One-word sentences (holophrases) at 1 year, two-word combinations at 2, simple grammatical sentences at 3. Vocabulary reaches 50–300 words by age 2 — about 50 words by 30 months is the referral threshold.
Erikson: toddler is autonomy versus shame and doubt; preschooler is initiative versus guilt. Piaget: sensorimotor gives way to preoperational around age 2.
Egocentrism and animism belong to this stage — she cannot take another viewpoint, and objects have feelings. That is why a preschooler reads illness as punishment.
Play is parallel in the toddler and becomes associative in the preschooler. Two 2-year-olds side by side with separate toys is exactly right for the age.
Head circumference is measured until age 2 unless there is a neurological concern.
📚 From your Maternal & Child textbook
Pillitteri, Maternal and Child Health Nursing — ch. 30 (toddler) · ch. 31 (preschooler).
Negativism and ritualism are normal toddler behavior, not defiance. The nursing response is limited choices — an open question hands a negativistic toddler the word no.
Preschool magical thinking means illness gets read as punishment, so saying plainly that it is not is a real intervention rather than just reassurance.
β οΈ Exam traps
Preschoolers interpret illness or a procedure as punishment β the intervention is reassurance, not just distraction.
Regression under stress is normal. Normalize it to the parents; do not treat it.
Ear assessment flips to up and back after age 3.

Built from this page's own content — the same four questions every time, so the shape is familiar before the topic is.
Toddler & Preschooler
🎯 The developmental task
Toddler (1–3) — Erikson: autonomy vs shame and doubt. "No" and "me do it" are the task, not misbehavior.
Preschooler (3–6) — initiative vs guilt. Endless questions and magical thinking.
Piaget: toddlers are sensorimotor into preoperational; preschoolers are preoperational and egocentric.
👀 What you see
Birth weight triples by age 1 and quadruples by age 2.
Anterior fontanel closes by 12–18 months.
Toddlers: parallel play. Preschoolers: associative and cooperative play.
Physiological anorexia and food jags in toddlerhood are normal; growth slows, so appetite does too.
🧪 What worries you
Injury is the leading cause of death in this age group — falls, drowning, poisoning, motor vehicles.
Choking risk: hot dogs, grapes, nuts, popcorn, hard candy.
Regression under stress or hospitalization is expected and temporary.
Not walking by 18 months, or no two-word phrases by 2 years, needs review.
🩺 What you do
Prepare a preschooler shortly before a procedure — long notice creates fear they cannot hold.
Offer limited real choices: "red cup or blue cup", never "shall we take your medicine?"
Allow the comfort object and a caregiver to stay.
Correct magical thinking: illness and procedures are not punishment, and say so plainly.

π§ What it isAlterations in Health (Diagnosis) Β· Health Promotion & Disease Prevention
Alterations in Health (Diagnosis)
Vaccines stimulate antibody production against a specific disease using a killed or weakened form of the organism. The Advisory Committee on Immunization Practices sets the schedule. Preterm infants receive each vaccine at the same chronologic age as full-term infants. A catch-up schedule on the CDC website covers missed doses. Goals are to reduce or eliminate infectious diseases in the population and to prevent those diseases and their complications.
Health Promotion & Disease Prevention
Hepatitis B: minimum age birth, 3 doses at birth, 1-2 months, and 6-18 months; at least 4 weeks between doses 1 and 2 and 8 weeks between doses 2 and 3; final dose no earlier than 24 weeks of age and at least 16 weeks after the first; withhold for preterm infants under 2,000 g if the mother is hepatitis B negative
Rotavirus: minimum age 6 weeks, 2 doses of Rotarix (2 and 4 months) or 3 doses of RotaTeq (2, 4, 6 months); do not start the series at 15 weeks0 days or older and give the last dose by 8 months0 days
DTaP: minimum age 6 weeks, 5 doses at 2, 4, 6 months, 15-18 months, and 4-6 years; at least 6 months between doses 3 and 4; dose 4 may be given as early as 12 months; dose 5 is unnecessary if dose 4 was given at 4 years or older and at least 6 months after dose 3
Tdap: minimum age 11 years, one dose at 11-12 years then Td booster every 10 years; one dose in each pregnancy between 27 and 36 weeks regardless of prior timing; for wounds, give Tdap or Td if a minor clean wound and over 10 years since the last dose, or over 5 years for all other wounds
Hib: minimum age 6 weeks, 4 doses (ActHIB, Pentacel, Vaxelis) at 2, 4, 6 months and a 12-15 month booster, or 3 doses (PedvaxHIB); use a different Hib product for the booster; only 1 dose is needed for unimmunized children 15 months or older
PCV13: minimum age 6 weeks, 4 doses at 2, 4, 6, and 12-15 months; follow current dual-series guidance with PPSV23 for high-risk conditions
π How it shows upAssessment β Risk Factors Β· Assessment β Expected Findings
Assessment β Risk Factors
From this module β built from the notes above on this page, not a section of the ATI chapter.
True contraindication: anaphylaxis to a previous dose or to a vaccine component.
Live vaccines (MMR, varicella, rotavirus, live influenza) are avoided in significant immunosuppression and in pregnancy.
Moderate or severe acute illness defers a dose; a mild cold with or without low fever does not.
Recent blood product or immunoglobulin can blunt the response to a live vaccine.
Egg allergy is not a contraindication to routine influenza vaccination, and a family history of reaction is not one either.
Assessment β Expected Findings
From this module β built from the notes above on this page, not a section of the ATI chapter.
Expected after a vaccine: low-grade fever, fussiness, and soreness, redness or a small lump at the site, for 1β2 days.
A small nodule at the injection site can persist for weeks and is harmless.
MMR and varicella may cause a mild rash or fever 7β12 days later, not immediately β parents need warning or they think it is unrelated illness.
Not expected: high fever, widespread hives, wheeze, facial or tongue swelling, or collapse. That is anaphylaxis.
π§ͺ How it is confirmedLaboratory Tests Β· Diagnostic Procedures
Laboratory Tests
From this module β built from the notes above on this page, not a section of the ATI chapter.
No routine bloodwork is needed before immunizing.
Titres may be checked to confirm immunity β rubella, varicella, hepatitis B β in health-care students and staff.
Hepatitis B surface antibody after the series in an infant of a positive mother.
Immune function testing before live vaccines where immunodeficiency is suspected.
Diagnostic Procedures
From this module β built from the notes above on this page, not a section of the ATI chapter.
None β immunization is a clinical decision from history and the schedule.
Review the record and use the catch-up schedule where doses are missing.
A lapsed schedule is resumed, never restarted.
Check the minimum interval between doses; too-early doses do not count.
Give the vaccine information statement and review it with guardians and older children, documenting each VIS publication date
Reassure caregivers that MMR is not associated with autism
IM route: vastus lateralis for infants and young children, deltoid for older children and adolescents
Subcutaneous route: outer upper arm or anterolateral thigh
Choose needle size by route, site, age, and volume β adequate length reduces injection site swelling and tenderness
Use comfort strategies to minimize discomfort
Effectiveness is shown by development of immunity and by local reactions resolving without pain, fever, or swelling
Anaphylaxis to any vaccine contraindicates further doses of that vaccine or any vaccine containing that substance
Medications
From this module β built from the notes above on this page, not a section of the ATI chapter.
Site by age:vastus lateralis for infants and toddlers, deltoid once the muscle is big enough, usually from about 3 years.
Needle length and gauge by age and muscle mass; 25 mm is common for infants.
Different vaccines go in different sites, or at least 1 inch apart, and are documented separately.
Epinephrine must be immediately available whenever vaccines are given.
Never mix vaccines in one syringe unless the product is licensed as a combination.
Therapeutic Procedures
From this module β built from the notes above on this page, not a section of the ATI chapter.
Comfort measures reduce distress and improve return rates: breastfeeding, sucrose, skin-to-skin for infants.
Hold the child securely with a parentβs help; give the injection quickly.
Observe for 15 minutes afterwards.
Older children: distraction, topical anesthetic, sitting up rather than lying down.
Give the most painful injection last.
π¬ Around the patientClient Education Β· Interprofessional Care
Client Education
From this module β built from the notes above on this page, not a section of the ATI chapter.
Give the Vaccine Information Statement before each vaccine β this is a legal requirement, not a courtesy.
Expect soreness and low fever; a cool compress and weight-appropriate acetaminophen or ibuprofen if needed.
Do not give an antipyretic prophylactically before the vaccine β it can reduce the immune response.
Return immediately for difficulty breathing, facial swelling, hives, or a child who becomes limp or unresponsive.
Keep the record and bring it to every visit; a lost record often means repeated doses.
Interprofessional Care
From this module β built from the notes above on this page, not a section of the ATI chapter.
Provider for the schedule and for judging true contraindications.
Pharmacist for storage and the cold chain β a break in it wastes the whole batch.
