1Physical difference between 2 and 6 year olds
They slim down, lower body lengthens, and fat is replaced by muscle. They lose the protruding belly, round face, short limbs, and large head, and center of gravity shifts from breast to belly
2Weight and height gain in early childhood by each year
Well-nourished children grow about 3 inches and gain almost 4.5 pounds
3Height and weight by age 6
At least 3 feet tall, weighs between 40-50 pounds, has adultlike proportions, and balances both sides of the body (running, hopping, etc)
4Nutrition in growth
Wasting and stunting are still possible, but the main problem is becoming overweight
5Causes of childhood obesity
Unhealthy snacks crowd out vitamins, food-insecure households, parents encourage eating, overeating, parents adding stress by criticizing eating
6Preventing overweight
Establish good nutrition (habit of eating healthy foods when hungry and not overeating), a balanced diet, prevention is easier than change
7Nutritional deficiencies
Most young children consume more than enough calories and sugar, but not enough vitamins and minerals
8Oral Health
Cavities and decaying teeth are a notable harm; toothbrushing and dentist visits should be habitual to prevent issues; also affected by diet and illness
9Allergies
~27% of US children have an allergy (4-8% worldwide), can be outgrown or deadly, small amounts of the substance can decrease allergies to it, and can complicate achieving a balanced diet.
10Brain weight by 6 years
90% of adult weight
11Myelination
The process by which axons become coated with myelin (white matter), a fatty substance that speeds transmission of nerve impulses from neuron to neuron
12Effects of myelin
Helps far away connections, organizes structure of network connectivity, regulates the timing of information flow, enables the use of many parts of the brain at once
13Lateralization
Literally, sidedness, referring to the specialization in certain functions by each side of the brain, with one side dominant for each activity. The left side of the brain controls the right side of the body, and vice versa
14Corpus Collosum
A long, thick band of nerve fibers that connects the left and right hemispheres of the brain and allows communication between them
15Myleination and corpuscallosum growth
Is more rapid than growth of the rest of the brain
16Entangled organ
Most important tasks require extensive interaction between hemispheres, lobes, and regions of the brain
17Corpus callosum maturation is _____ and causes _____
plastic; causes better thinking, less clumsiness, and reading, writing, and addition skills
18Failed corpus callosum development
Serious disorders occur, a common symptom of autism, and growth is epigenetic
19Left-handedness
Tend to have thicker, better myelinated corpus callosa than right-handed people due to having to switch between the sides of their bodies
20Maturation of the prefrontal cortex
Sleep becomes more regular, emotions become more nuanced and responsive, tempertantrums subside, and uncontrollable laughter and tears are less common
21Neurons two ways of responding
activate (on) or inhibit (off), signaled by biochemical messages from axons and dendrites, balance is necessary for thoughtful adults
22Impulse Control
The ability to postpone or deny the immediate response to an idea or behavior, a lack of it signifies a personality disorder in adults, but not in early childhood
23Perseveration
To stay stuck, or persevere, in one thought or action for a long time. The ability to be flexible, switching from one task to another, is beyond most young children
24Relationship between stress and brain activity
Depends partly on the age of the person and on the degree of stress
25Stress in children
Mild stress can benefit cogntion but intense stress can cause negative mental stress (dim consciousness, narrowed scope of consciousness, impaired attention, etc.) When stressed, they need routines
26What adults must provide when a child a stressed
Reassurance, warm and attentive listening
27Motor skill development
Brain maturation and myelination directly contribute
28Early childhood gross motor skills
Improve markedly, can perform coordinated dance steps, tumbling tricks, or sports moves, ride a tricycle, climb a ladder (requires balanced coordination and both hemispheres)
29Play
Is crutial for every aspect of child development, especially outside play, which develops running, climbing, leaping, and jumping
30Early childhood fine motor skills
Also improves, practice of these can advance cognition, and there are evident gender differences (girls are more likely to be given tasks that advance these)
31Trauma in early life...
affects development lifelong
32Injury control/harm reduction
Practices that are aimed at anticipating, controlling, and preventing dangerous activities; these practices reflect the beliefs that accidents are not random and that injuries can be made less harmful if proper controls are in place
33Three levels of prevention that apply to every health and safety issue
Primary prevention, secondary prevention, and tertiary prevention
34Primary prevention
Actions that change overall background conditions to prevent some unwanted event or circumstance, such as injury, disease, or abuse
35Secondary prevention
Actions that avert harm in a high-risk situation, such as stopping a car before it hits a pedestrian
36Tertiary prevention
Actions, such as immediate and effective medical treatment, that are taken after an adverse event and are aimed at reducing harm or preventing disability
37Biggest cause of child death
Passengers in cars
38Prevention in motor vehicle deaths
Primary: sidewalks, overpasses, streetlights, traffic circles, safer cars; Secondary: crossing guards and flashing lights on stopped school busses, salt on icy roads, speed bumps, and car seat laws; Tertiary: fewer hit and run drivers, speedier ambulances, better emergency procedures
39Preventing gun deaths
Accidental gun death (1-4 years) is higher in the US than anywhere else, caused by increases in gun availability, owners dont store, unload, and lock up guns,
40Prevention begins by
considering the nature of the child
41Preventing injury from the environment
Law and policy also need to be considered; air pollution has been reduced in NA, many pesticides are banned from home use, and foods are regulated
42Blaming the caregivers
Caregivers are important, but cultures and corporations may be crucial for primary prevention and injury control
43Childhood disease deaths
Have been decreased markedly with immunization, new treatments, and better nutrition, and accidental deaths are decreasing as well, but deliberate child harm has not been reducing
44Battered child syndrome
Findings of prior bone breaks, forceful burn patterns, scars from past pain, explanations that were implausible
45Causes of child maltreatment
Not rare nor sudden, over 90% of perpetrators are the child's parents
46Child maltreatment
Intentional harm or avoidable endangerment of anyone under 18 years of age. Includes child abuse and child neglet
47Child abuse
Deliberate action that is harmful to a child's physical, emotional, or sexual well-being
48Child neglect
Failure to meet a child's basic physical, educational, or emotional needs. Most common and frequently fatal form of child maltreatment
49Substantiated maltreatment
Harm or endangerment that has been reported, investigated, and verified. Annual rate of 2-5 year olds is more than 1 in every 100
50Reported maltreatment
Harm or endangerment about which someone has notified the authorities. More are this than are substantiated
51Causes for more reported maltreatment than substantiated
Substantiation requires proof, about 1/3 of reports are screened out as not about a child or for another jurisdiction, 2/3 of all reports come from professional mandated reporters, each child is only counted once (6 reports=1 substantiated case), or a report may be false/misleading
52Underlying risk factors for substantiated maltreatment
Social isolation and economic, both of which increased during the COVID pandemic
53Signs of child maltreatment (neglect and abuse)
Slow growth, immature talk, lack of curiosity, odd social interaction, injuries unlikely to be accidents, repeated injuries, violent or sexual fantasy play, unusual or little appetite, ongoing physical complaints, and more
54Consequences of maltreatment
Regard people as hostile, making them less friendly, more aggressive, and more isolated. The earlier it starts and the longer it continues, the worse social relationships are lifelong
55Primary prevention in child maltreatment
The ultimate goal; neighborhood stability, caregiver education, income support, and fewer unwanted children all reduce maltreatment via this type of prevention.
56Secondary prevention in child maltreatment
Insecure attachment should be repaired before it becomes harmful
57Tertiary prevention in child maltreatment
Reporting is the first step, and repairing is the second. The final step is getting better care for the child
58Permancy planning
An effort by child-welfare authorities to find a long-term living situation that will provide stability and support for a maltreated child. A goal is to avoid repeated changes of caregiver or school, which can be particularly harmful to the child
59Foster care
A legal, publicly supported system in which a maltreated child is removed from the parent's custody and entrusted to another adult ot family, who is reimbursed for expenses incurred in meeting the childs needs
60Kinship care
A form of foster care in which a relative of a maltreated child, usually a grandparent, becomes the approved caregiver
61Adoption
Sometimes the ideal permanency plan. Not the most common due to judges/ bio parents being reluctant to release children, more adoptive parents prefer newborns, some agencies screen out unmarried families, and some agencies require that adoptive parents have the same ethnic or religious background as the child
