Factors That Define an Infant as Being High Risk, Periods of Growth Factors That Define an Infant as Being High Risk Demographic Social Factors: Maternal age 40 years Illicit drugs, alcohol, cigarette use Poverty Unmarried status Emotional or physical stress Past Medical History: Genetic disorders Diabetes mellitus Hypertension Asymptomatic bacteriuria Rheumatologic illness (e.g., systemic lupus erythematosus) Immune-mediated diseases (e.g., immunoglobulin G crossing the placenta) Long-term medications Timeline for Primitive Reflexes Reflexes and Their Characteristics: 1. Palmar Grasp: Onset: 28 weeks of gestation Fully Developed: 32 weeks of gestation Duration: 2-3 months postnatal 2. Rooting: Onset: 32 weeks of gestation Fully Developed: 36 weeks of gestation Duration: Less prominent after 1 month postnatal 3. Moro: Onset: 28-32 weeks of gestation Fully Developed: 37 weeks of gestation Duration: 5-6 months postnatal 4. Tonic Neck: Onset: 35 weeks of gestation Fully Developed: 1 month postnatal Duration: 3-4 months postnatal 5. Parachute: Onset: 7-8 months postnatal Fully Developed: 10-11 months postnatal Duration: Remains throughout life Note: There is variation in the duration of the tonic neck reflex based on the reference used; it may disappear by 4 months (Ghai Essential Pediatrics) or 6 months (Nelson Pediatrics). Periods of Growth Prenatal Period: Zygote: 0 to 14 days of gestation Embryo: 3 weeks to 8 weeks Fetus: 9 weeks to birth Perinatal Period: 22 weeks to 7 days after birth Postnatal Period: Newborn (Neonate): First 4 weeks after birth Infancy: The first year Toddler: 1 to 3 years Preschool Child: 3 to 6 years School-Age Child: 6 to 12 years Adolescence: Early: 10 to 13 years Middle: 14 to 16 years Late: 17 to 19 years Periods of Growth Growth and Development: Key Definitions and Timeframes 1. Prenatal Period: Zygote (0 to 14 days of gestation): This stage represents the earliest development post-fertilization. It covers the time from the fertilized egg's journey to the uterus until it embeds itself in the uterine wall. Embryo (3 weeks to 8 weeks of gestation): During this critical period, organogenesis occurs, where the basic structures of the body's organs start forming. Fetus (9 weeks to birth): Growth and development continue, and this phase is characterized by rapid body growth, organ maturation, and further specialization. Perinatal Period (22 weeks of gestation to 7 days after birth): This stage spans late fetal development, labor, and the first week of life, emphasizing the transition from intrauterine to extrauterine existence. 2. Postnatal Period: Newborn (Neonate) – First 4 weeks after birth: Neonates adapt to life outside the womb, focusing on basic survival functions like feeding, breathing, and thermoregulation. Infancy – The First Year: A period marked by rapid physical growth, sensory and motor development, and the beginning of cognitive and social interaction. Toddler – 1 to 3 years: Characterized by enhanced motor skills, language acquisition, and increased independence. This phase often includes the infamous "terrible twos," where behavioral outbursts are common as children test boundaries. Preschool Child – 3 to 6 years: This stage includes further refinement of motor skills, imaginative play, early literacy, and foundational learning. Social skills develop rapidly, and children start forming peer relationships. School-Age Child – 6 to 12 years: A period where cognitive and physical development continues steadily. Children develop critical thinking skills, more complex social relationships, and academic skills. 3. Adolescence: Early Adolescence (10 to 13 years): Characterized by the onset of puberty, rapid physical growth, and significant emotional and psychological changes. Middle Adolescence (14 to 16 years): A phase of continued physical maturation, increased independence, exploration of identity, and heightened peer influence. Late Adolescence (17 to 19 years): This period sees the final stages of physical growth and psychological development, with young adults transitioning into more defined roles in society and relationships.
