Infant Feeds Flashcards
Why is Nutrition Important?
- Fundamental aspect of life
- First 1000 days of life – provide best start to life
- Growth not just about increasing size but change in brain and body structure, composition and function
- Good nutrition prevents disease
what are the recognised phases of childhood?
- Neonate (<4w)
- Infant (<12m/1y)
- Toddler (~1-2y)
- Pre-school (~2-5y)
- School age
- Teenager/ Adolescent
Phases of Growth:
- Infant – _________ led
- Child – _______ _________ led
- Pubertal – ___ ________ led
nutrition
growth hormone
sex steroid
Birth size and weight depends on what things?
- Maternal size (Small mother wouldn’t really have a really big baby)
- Placental function (Problem with placenta function in utero = not as big as a baby)
- Gestation (preterm = smaller)
- More than genetic make up
- Average term infant 3.3 kg
Mother diabetic = bigger baby born
Nutritional Requirements - why?
- Energy is needed for: Physical activity, Thermogenesis, Tissue maintenance (repair of any damage), Growth
- Energy requirement = energy expended + energy deposited in new tissue
- Growth demands - about 35% of energy intake in infants but falls for rest of childhood
Infant Nutrition:
•Characteristic feature is the need to fuel both rapid growth and maintenance
what risks are there?
Infants can rapidly become malnourished.
Dependent on carer
High demands for growth and maintenance
- infants 100kcal and 2g protein/kg/day
- adults 35kcal and 1g protein/kg/day
Low stores (Fat and protein)
Frequent illness (if unwell then they don’t want to feed and can then lose weight and can impact on growth)
what is average weight gain?
- 0-3months 200g
- 3-6 months 150g
- 6-9 months 100g
- 9-12 months 75-50g
- Double weight by 6 months and triple by 1 year
- After 1 year approx 2kg and 5cm/year until puberty
- 4kg baby with 4 weeks of static weight ,20% underweight, like an adult losing 20kg.

Why is Breast best?
•Nutritionally complete feed for full term babies
- Well tolerated
- Less allergenic
- Low renal solute load
- Ca:PO4, Iron, LCP FAs
- Improves cognitive development
- Reduces risk of infection
Best nutrition
Breast milk vs. Formula
what age should breastfeeding be done?
- Recommended to exclusively breast feed to around 6 months of age
- From 6 months, complementary breast feeding alongside solids is supported
If Breast Feeding is not possible what should be done?
- Families who formula feed should be supported to do so as safely as possible
- Standard formula are cows milk based
- Various brands available - No significant difference, Use whey dominant “first milks”
- Powder or ready to feed
- Various compositions based on age
- Milk is the exclusive feed for 4-6 months (breast milk or formula)
- Breast is Best- WHO recommendation
What are the Types of Milk for Infants?
- Standard formula (Cows milk based)
- Specialised - for cows milk protein allergy, nutrient dense, disease specific
- Cows milk not as main drink until 1 year - Contains no iron (runs risk of iron deficiency anaemia)
Other formulae - Pre-term formulae, Nutrient dense formulae, Cows milk protein allergy, Disease specific
Normal feeding patterns - how does the number of feeds per day change with age?
decreases
What is used if there is Cows milk protein allergy?
•First line feed choice (top photo)
- Extensively hydrolysed protein feeds
- 90% should respond (10% react)
- Palatability a problem in older babies
•Second line feeds (bottom photo)
- Amino acid based feeds
- Babies with severe colitis/enteropathy/symptoms on breast milk
what is the milk ladder?
1 year – increasing small amounts of dairy in diet
Start with biscuit with small amount of milk powder in it as you tend to tolerance a milk derivative that has been cooked well
Heat processing will denature the protein so you tend to tolerate that better
Moves up to a less processed and bigger dose of dairy
Ultimate goal is to reach milk as cows milk at the top of the ladder
Lactose Free Milks - what is lactose intolerance?
Not allergy.
Reduced levels of the enzyme (lactase)
Seen to minor degree in some breast fed babies
Post gastro enteritis (Transient and self resolving)
Also in certain ethnic groups post weaning
Lactose Free Milks can also be used For secondary lactose intolerance, what is it?
Short lived condition eg post gastro-enteritis
Confused with cow’s milk protein intolerance
Lactose free/ “Comfort” milks are not CMP free
