Complementary feeding

Defined as the process starting when breast milk alone is no longer sufficient to meet nutritional requirements, and therefore other foods and liquids are needed along with breastmilk or formula

Ready to fee… around 6 months of age

-Nutrient needs no longer met by breastmilk
-Reached a developmental stage whereby the infant is able to initiate solid foods
-Texture, variety and flavour introduction and motor development of self feeding are important components of enhancing cognitive development

Newborn:

-Infants are born with reflexes that prepare them to feed
-Rooting, mouthing, head turning.gagging, swallowing and coordinate breath and swallow

Increased risk of

Eczema and food allergies
Respiratory disease

Eruption of teeth

when the baby is around six to nine month old

Teeth are not necessary for an infant to start on solid food- strong gums

Sensitive period for texture development

Prolonged use of puree foods (>9 months) and introducvtion of lumpy foods later than 10 months is associated:
- Feeding difficulties (commonly refusal) in older children
-Low intake of nutrient rich foods

WHO complementary feeding

6-8 months

-Milk given before food
-CF given 2-3 times per day (200kcal/d based on decreasing BM energy)

WHO complementary feeding

9-11 months

-CF 3 times per day with 1-2 nutritious snacks (-686 kcal/d)
-Milk given after food (top-up)

Responsive feeding

-Sensitive to hunger and satiety cues

-Feed slowly and patiently and encourage children to eat but not force them

-If child refuses food, experiment with different food combinations, tastes, textures and methods of encouragement

-Feeding time is period of learning and low (talking and eye contact)

5 Signs a baby is hungry

Opening mouth (seeking and rooting reflex)
-Fussing and leaning toward breast or food
-Increased physical movements that become agitated /exited
-Crying in a distressed, intense way
-Asking for or pointing at foods

5 signs baby has had enough

Study These Flashcards

-Pushing or arching away, pushing food or plate away
-Turning head away or shaking head to communicate ‘no more’
-Spitting out food
-Using words like ‘all done or get down’
-Becoming distracted and more interested in what is going on around them

MOH recommendation

recommended serving sizes ….

Once complementary fooda are introduced…..

Study These Flashcards

Recommended serving sizes for this age group are not given

Once complementary foods are introduced, the emphasis should be on growth and development, choice and texture, and appropriate eating behaviours and patterns

what are the two main things to feed a baby at 6 months so that they are able to get the iron required

Study These Flashcards

Cooked pureed meat or even just the juices of the meat

baby rice cereal: iron-fortified cereal mixed with water, breast milk or formula

Conflict on baby rice

Study These Flashcards

Some nutritionist do not recommend baby rice as it is processed (Amylase and Arsenic)

Amylase By the time a baby is 6 months they have the same amount of amylase as a adult

-Arsenic you would need to consume 90g for it to be concern. The average consumption by NZ infants a day is 7g

Importance of iron Iron Deficiency is prevalent in infancy due to:

-High requirement- High growth rate -Iron stores received in utero begin to run low

Infants most at risk of iron deficiency:

-Low intake of high iron foods -low birth weight -Preterm infants -Low socioeconomic status/food insecure whanau

Breast milk iron is highly bioavailable but ....

still not sufficient for a growing baby

Iron deficiency in how many NZ infants

n-364 NZ infants aged 7-8 months

Consequences of iron deficiency

-altered intestinal function -Impaired cognitive, social and socio-emotional development

Iron deficiency anaemia

-Fatigue / decreased activity - Sustained IDA may be associated with irreversible and detrimental effects on intellectual and motor performance

Prevention of iron deficiency

-Food first approach - Iron supplementation for healthy young children

First foods -Vegetables and fruit

-provide important nutrients- Vitamins, minerals, fibre -Early childhood intakes of vegetables and fruits improves immunity, aids digestion, decreases risk of obesity -Offer variety of colours (repeated exposure necessary - acceptance)

Repeated exposure

Can take around 8 to 15 exposured before acceptance any exposure -see, touch, smell, taste

Tastes

preference for sweet tastes - Just like breast milk Offering vegetables as first foods improves acceptance of these vegetables at 9 months

Fluids

Breastmilk or formula Other than these water is the only other fluid that should be given

Preparing foods -flavours

Infants and adults have different taste buds, foods may taste bland to you but not to them Do not add salt, soy sauce, sugar, honey or artificial sweeteners to infants foods

Avoid honey

Honey should not be fed to infants <12 months Can cuase infant botulism cuased by the toxin Clostridium botulinum Survives cooking temps so should also not be added during cooking

Immuture guts are susceptible to food borne illnesses

-Wash hand with soap and dry thorouly -wash equipment thorouly in hot soapy water -sterilise equipment until infant is 6 months old -Container should be kept in fridge for no more than 48hr -Throw out food that has been sitting in room temp for >2hrs

Gagging

-Watering eyes -Pushing tongue forward -Retching movement to bring food forward -May vomit =loud / dramatic

Chocking

-May cough or gasp as trying to get air -May go silent -May make a struggling sound or raspy whisper =Silent

Minimise risk -chocking

-Supervision -offer food that matches their abilities -alter food texture -Caregivers need to learn CPR -Be aware of foods that are more likely to cause chocking

Foods that are very susceptible to chocking

-Small hard foods -Small round foods -Foods with skin or leaves -Compressible food -Thick pastes -Fibrous or stringy foods

Infant formula for special dietary use Infants with cows milk protein allergy : require...

Require extensively hydrolysed infant formula -Treated with enzymes to break down most of the cows milk protein

How to purchase Dietary option

Can often be purchased over the counter (without prescription) -> to change under "proposal P1028"

Cows milk should not be given as a drink until infants are older than why?

one year (>12 months) -concentration and bioavailability of iron is low -May cause gastrointestinal blood loss (infants cant tollerate the high mineral content in cows milk) High renal solute load May replace other solid foods, reducing nutrient intake

Pathophysiological mechanism

-Undefined -Immunological mechanism likely plays a role -Five major protein in cows milk: ????

Cows milk and renal solute load

Cows milk has quite a high mineral content compared to human milk so the kidneys are relied on to manage the mineral concentration of cows milk which is difficult for an infant due to their immature kidneys

Cows milk in food

This is ok its more the high concentrations that is the issues

When baby is unwell : reduced intake can be concerning for caregivers

Consider inatke over the week rather than the day Important to remain hydrated - Regular offering of breat milk (or formula) and water -Small portions of soft foods (easy to swallow)

Baby food pouches occupy ... Concerns energy...

Occupy a lot of supermarket space Concerns about adverse health outcomes -Dietition concerns: cannot see, touch or smell pouch contents Energy contributes to weight gain due to high sugar content

Two approaches to starting solids

Spoon Feeding or Baby led weaning
