Developmental Markers

  1. Infants:
    • Solitary play
    • Stranger anxiety, onset as early as six months and peaks around eight months.
    • Wean into solid foods by six months.
    • Aspiration risk is present during infancy during the oral phase of psychosexual development; they will bring any object they are able to hold to their mouths.
    • Dentition: six months onwards— lower central incisors (six months), upper central incisors (seven months), upper lateral incisors (nine months), lower lateral incisors (eleven months)
  2. Toddlers:
    • Parallel play
    • Negativistic, the tendency to say “No” in order to exercise autonomy. Intervene by provision choices rather than requests that can be answered with “No”.
    • Throwing Tantrums: a result of the inability to express their frustration. Intervene by ignoring the behavior while maintaining safety.
    • Separation anxiety: an intense fear of abandonment with three distinct phases— (a) protesting manifested by crying, screaming, etc., (b) despair manifested by isolation, anorexia, and withdrawal, and (c) denial, manifested by the toddler ignoring the returning caregiver to “deny” their feelings of anxiety. Intervention to reduce anxiety involves not prolonging departure, the provision of security objects/blankets, and informing the child when the parent will arrive (making sure that the toddler understands).
    • Physiologic anorexia: distractions from exploration may result in physiologic anorexia
    • Push-pull toys
    • Autonomy vs. Shame and Doubt
    • Dentition: completion of deciduous teeth (20 teeth) by two and a half years old. This is the best time to begin dental visits.
  3. Preschooler:
    • Associative play
    • Fears of Mutilation/Castration, and the Dark/Ghosts from magical thinking. They become aware of the reality of death.

Newborn Assessment

ParameterNormal RangeDeviations
Birth Weight2.5 - 4.0 kgLow Birth Weight (<2.5 kg), Very Low Birth Weight (<1.5 kg), Small for Gestational Age (<10th percentile), Large for Gestational Age/Macrosomia (>90th percentile)
Birth Length45 - 55 cm
Head Circumference33 - 35 cmHydrocephaly, Microcephaly
Chest Circumference31 - 33 cm
  • The chest circumference becomes larger than the head circumference >1 year old.
  • Birth weight doubles by six months of age, triples by twelve months of age, and quadruples by two years of age.
  • Birth length doubles by four years of age, and triples by thirteen years of age. Growth ends at around 21 years old because of the closure of the epiphyseal growth plates.

Skin Assessment

  1. Mongolian Spots are bluish-grey spots at the buttocks or lower back. This is caused by an increased melanocyte count. This is common among asian newborns. These spots disappear by school-age, but remain for life in 10% of cases.
  2. Talengiectasia Nevii (“Stork Bites”) are pink pale patches at the nape or forehead due to overstretched blood vessels under the skin and are not a cause of concern. This disappears by two years old.
  3. Nevus Vasculosus (“Strawberry mark”) are masses that are red and raised with rough edges commonly found on the forehead. They are formed from clumped blood vessels and tissues forming a benign mass. These often disappear from seven to nine years of age.
  4. Nevus Flammeus (“Port Wine Stain”) are red-purplish marks seen on the face due to abnormal formations of small blood vessels under the skin. The mark is appears as if the face was stained by wine. Uniquely, this mark does not usually disappear, with its color darkening as the individual grows older.
  5. Erythema Toxicum Neonatorum: is a normal newborn rash that may appear all over the body with an unknown cause, but is associated with an increased eosinophil count. The rash disappears within weeks.
  6. Milia (“Milk Spots”) are white pinpoint papules on the nose, chin, or cheeks due to immature, distended sebaceous glands. These also disappear within weeks.

Ear/Hearing Assessment

  1. Appearance: the ears should be symmetrical and is structured with a firm cartilage with quick recoil.
    1. In preterm newborns, ear recoil is slow; the ears, if folded, will take a few seconds to return to its original position.
    2. In children with down syndrome (Trisomy 21), ears are low-set. Their position in relation to the eyes (normally at the same level) is low.
  2. Retrolental Fibroplasia (Retinopathy of Prematurity): a complication of oxygenation therapy when high concentrations of oxygen is delivered to the infant (>40% O2). This may result in blindness. It is known as the retinopathy of prematurity (ROP) because premature babies often require oxygenation. In oxygen therapy, blood vessels in the eyes will begin to proliferate abnormally, which can result in blindness.

Mouth Assessment

  1. Epstein Pearls are white glistening cysts at the upper palate that appear as “pearls”. These are due to trapped keratin and epithelial tissues forming a bump or cyst. This will disappear within weeks and are not a cause of concern.

Nose Assessment

  1. Choanal Atresia: an abnormality manifested by mouth breathing in the newborn. Mouth breathing is always an abnormality. This is a developmental abnormality wherein the nasal passages do not form; a channel between the nasal cavity and the oral cavity (the choana), is blocked by bone and mucous membranes.
  2. Nasal Flaring: enlargement of the nose, with potential redness. This is always a sign of any disorders in respiration as the body attempts to improve ventilation.

Chest Assessment

  1. Witch Milk, the production of breastmilk by newborns (of either gender) as a result of exposure to maternal hormones, and disappears within weeks once hormonal levels return to normal.

Genitourinary Assessment

  1. Voiding within 24 hours should occur within a newborn.
  2. In females, an edematous labia/clitoris is normal in newborns.
  3. In females, pseudo-menstruation may occur due to the withdrawal of maternal hormones that the newborn was exposed to in-utero. This also disappears within weeks once hormonal levels return to normal.
  4. In males, the scrotum should have rugae. A smooth scrotum is commonly seen in premature newborns.
  5. In males, the testicles should be palpable. If these are not palpable, cryptorchidism (undescended testicles) may be present and is an abnormal finding. If the testicles do not descent, spermatogenesis will not occur due to body heat resulting in sterility. This may also result in testicular cancer.
    • Risk factors for cryptorchidism includes prematurity and maternal caffeine intake during pregnancy.
  6. In males, the meatus should be at the tip of the glans. This may be malformed to an area dorsal (above from a side-view) to the expected anatomical location, known as epispadias or ventral (below from a side-view) to the expected anatomical location, known as hypospadias.
    • If either disorder is present, circumcision is delayed as the corrective surgery for the disorder may utilize the excess skin for reconstruction.

Back Assessment

  1. Spina Bifida: an abnormality of the spinal column where a segment of the spinal bone fails to close, leading to an outpouching of spinal contents, which may include nerves, spinal fluid, blood vessels, etc.
    • Spina Bifida Occulta: a “covert” form of the disorder where the outpouching is not evident, except through some skin dimpling or a tuft of hair. This form may allow the individual to live a normal life with no complications.
    • Spina Bifida Cystica: an “overt” form of the disorder where the outpouching forms a sac. Depending on the contents of the contents of the sac, it may be further classified as a meningocele or a myelomeningocele (contains spinal nervous contents). In the absence of nervous contents in a meningocele, no motor or sensory loss occurs. Functional loss occurs in a myelomeningocele due to the involvement of spinal nerves, potentially resulting in paraplegia/paraparesis and bowel/bladder problems.
    • A major risk factor for congenital spinal abnormalities are those mothers who are deficient in Vitamin B9 (Folate)/Folic Acid found in green leafy vegetables.

Hip Assessment

  1. Developmental Hip Dysplasia: a misplacement of the femur from its normal anatomical position. This is tested with Allis/Galleazi/Ortolanis sign. This procedure lies the child supine, flexes the hips and knees, then abducts the knees. A distinct clicking sound is heard as the femoral head clicks back into place in contact with the acetabulum.

Cardiovascular Assessment

  1. Coarctation of the Aorta: a malformation of the ascending aorta where a segment of the aorta constricts. This results in hypertension, bounding pulses, warmth, etc. in the upper body supplied by the branches of the ascending aorta, and hypotension, weak pulses, cool clammy skin, etc. of the lower body supplied by the descending aorta. This is a characteristic presentation of a coarctation of the aorta.
    • Increased upper body blood flow can result in epistaxis.
    • Treatment: resection and end-to-end anastomosis of the constricted section.
