Tasks During Infancy (Birth to 1 Year)

• Infants learn to lift their heads, roll over, sit up, crawl, stand, and walk
• Walking builds independence and exploration
• Around 6 months, babies transition from milk/formula to pureed solid foods
• Essential for meeting nutritional needs and developing oral motor skills with new tastes and textures
• Early communication includes cooing, babbling, gestures, and simple words
• Language development is influenced by how much the baby is spoken to and engaged with
• By the end of the first year, many babies say simple words like “mama” or “dada”

• Parents or caregivers guide these patterns

Neoate or Newborn (Birth to 28 Days)

• The neonatal period marks the first 28 days of life being a critical adjustment time

Neurological & Movement Development:

• The central nervous system is immature at birth, causing jerky and uncoordinated movements without clear purpose
• Motor control improves over time as the brain and nerves mature

Sensory Abilities:

Nutrition and Feeding:

• The main diet is breast milk or infant formula during the first 6 months which provides nutrients and immune support
• Solid foods can be gradually introduced around 5–7 months, depending on readiness
• New foods must be introduced one at a time to observe for allergic reactions

Newborn Reflexes (Involuntary Movements):

• Primitive reflexes are essential survival mechanisms and indicate neurological development that gradually disappear as voluntary control develops.
• The Moro reflex (startle reflex) is triggered by a loud noise or sudden movement
• Babies respond by throwing arms and legs outward, followed by pulling them back in and crying, typically fades by 4–6 months
• The rooting reflex is triggered when the baby’s cheek is stroked that results in the baby turning their head toward the touch, opens their mouth, disappears by 4 months

Infant Diet Overview: Birth to 6 Months

• Primary nutrition comes from exclusively breastmilk or formula, with breastmilk providing essential antibodies and nutrients
• Solid foods consisting of strained fruits, vegetables, cereals) are introduced, starting on one food at a time to monitor for allergies
• Solids should not replace milk but supplement it
• By 9-10 months start introducing chopped soft foods, with more and varied textures where the infant may eat 3 meals and snacks daily with milk
• By 1 year babies can eat most table foods cut into safe, small pieces and drinks from a cup and may begin using utensils.

Caregiver Role & Responsibilities: Emotional & Physical Care

• Infants are completely dependent on caregivers for feeding, diapering, comfort, and safety
• Caregivers should respond to cues like crying, fussing, or smiling

Support Worker Guidance

• Ensure a safe environment that follows safe sleep practices with no small objects
• Promote developmental growth by engaging with the infant with talking, reading singing or play
• Support both physical (feeding, bathing, sleeping) and emotional needs (bonding, soothing, touch).

Hygiene & Health: Hand Hygiene

• Infants have an immature immune system
• Everyone who touches or handles infants should wash hands thoroughly while avoiding contact when sick.
• Regularly clean feeding equipment and toys

Comforting the Crying Infant

• Crying is a normal and healthy way for infants to communicate their needs, indicating discomfort, distress, or emotional needs.
• The common reasons babies cry is related to Hunger from small stomachs needing feeding frequently
• Wet or soiled diapers may cause skin irritation and discomfort
• Temperature Discomforts from being too hot or too cold
• Fatigue is common and can be a result
• Pain or illness is causes such as teething, gas, colic, or a more serious medical concern.
• Loneliness or need for comfort and reassurance

Key Care Principle

• You should respond to a baby's crying immediately to help them feel safe, secure, and supported
• Meeting an infant’s needs promptly builds trust, supports emotional development, and reduces long-term stress

Guidelines for Soothing a Crying Infant

• Start with a checklist to meet all physical needs by first ensuring a clean diaper followed by feeding and checking temperature and signs of tiredness or illness

Comforting Techniques

• Utilize gentle, rhythmic motions that mimics what they experienced in the womb (rocking, swinging, or walking)
• Provide close physical contact and ensure warmth
• Massage and apply gentle touch such as rubbing the baby’s back or stomach in slow, gentle circles. This can relieve gas or general fussiness
• Swaddle the baby to mimic of the womb while ensuring the swaddle is snug but not too tight, with loose hips to prevent hip dysplasia

Infant Care Techniques

• Pay a particular attention to hygienic measures because Newborns have underdeveloped immune systems make them highly vulnerable to infections
• Wash hands before and after touching or handling the baby and use sanitizer if soap and water are unavailable
• Handle the baby with Gentle Smooth Movements that helps prevent triggering of the startle reflex
• Avoid Sudden or Jerking Movements because Infants are easily startled leading to crying and discomfort
• Full-Body Support helps babies stay secure and protected. Support must be given for the newborn’s head and neck at all times

Bottle Feeding Techniques

• Formula comes in three forms, ready to feed that requires no mixing or preparation, Powdered that requires water and must be measured and mixed, and concentrated and must be diluted as directed
• Bottles can be prepared one at a time or as daily batches by following container instructions closely for safe and accurate preparation.
• Prepare bottles and store in the refrigerator for no more than 24 hours
• Wash formula containers before opening and ensure baby bottles, nipples, and other feeding equipment is as ideally sterilize

Feeding Techniques

• Infants should be fed every 3 to 4 hours
• Warming cold formula is generally preferred by babies, put few drops inside of your wrist to feel warm from from the temperature test
• Burping helps babies relieve discomfort and prevent them from swallowing air during feeding (2 to 5 minutes with gentle rubs or pats)
• Burping positions include over the shoulder, sitting on your lap (always supporting the head and neck, or lying stomach-down on your lap

Diaper Change Techniques

• Start by identifing the general stool characteristic of the baby, breast milk or bottle
• Address Hard stools from constipation or diahrrea from illnesses right away
• Cloth diapers must be changed in when soiled or wet with special care instructions
• Disposeable diapers secured with velcro or tape should be changed in the garbage only

Bathing Techniques

• Promotes hygiene, comfort, bonding, and relaxation for babies.
• Planning is critical, do no leave babies unattended during baths
• Follow bath instructions and guidance as determined in the careplan

Sleep Saftey

• Prevent Sudden Infant Death Syndrome (SIDS) by laying infants down to sleep on their backs only while following careful sleep practices
• Avoid Soft Bedding and Surfaces that increases the risk of carbon dixoide buildup and accumulation
• Keep the sleep space clear of harmful risks in the crib

Temperature Regulation

• Overheating is a risk factor for SIDS
• Avoid the use of heavy blankets and over dressing the baby
• The room temperature should be kept cool and comfortable for adults
• Signs of over heating are:
• Sweaty neck or back
• Flushed Skin
• Restlessness or rapid breathing

Shaken Baby Syndrome

• Shaken Baby Syndrome is the use of abusive head trauma (AHT) when violently shaking the baby can cause severe damages
• Infants have:
• Weak Muscles - causing difficulty to support the head and neck
• Large head that promotes collision with skull with shaking causing possible: Brain bruising & Swelling, bleeding
• Prevent further possible trauma of baby and never shake a baby ever.

Fall Prevention

• Take great care and remember that falls can occur out of knowere at any time no matter how nearby you are.
• Take steps to safe guard risk factors for Rolling Off Surfaces.
• Use the safety guards, stay attentive and one guard close to baby at risk factors like tables, countertops, raised sufaces etc.
• Install Safety devices and sturdy supports on equipment such as: stairs, cribs, table tops and safety harnesses.
• Do not give into high-risk foods that cause Prevent Choking during meals by preparing food safely, watching the child and knowing what foods to stay away from.
• Remove risky small objects and Propped feeding, and lastly make sure to follow preventative measures to ensure they have happy and safe life.
• No small objects
• Prevent propped feeding

Precautions around liquids and heat

• Follow prevention that includes not walking near or over infants while holding hot drinks or food
• Place objects at saftey from edges and heat at the correct warmth
