This presentation deals with classification of infants based on health, types of feeding methods, choice of milk for low birth weight infants, Needs for feeding, nonnutritive sucking, and growth chart. It will give short and crisp materials related to above topic.

1. FEEDING THE PREMATURE AND LOW BIRTH
WEIGHT INFANTS

2. Full term infant
 Baby born with the ability to efficiently extract milk from the breast or bottle.
 Physical and neurological development allows the full-term infant to maintain
efficient posture for feeding, generate appropriate oral pressure for milk
extraction, coordinate suck-swallow-breathing and regulate sleep-wake cycles
in a manner that facilitates demand feeding.

3. Premature infant
 Infant born prematurely has low tone, decreased muscle and fat mass, does not
effectively coordinate suck-swallow-breathing, and does not sustain prolonged
wake states.
 This places the infant at a disadvantage for being an efficient feeder.
 Globally, about 18 million infants are born with a birth weight of < 2500g every
year.
 Low birth weight infants constitute only about 14% of the total live births, they
account for 60-80% of total neonatal deaths

4. Nutritional management influences immediate survival as well as subsequent
growth and development of LBW infants.
Limitations:
 Pre-term infants born with inadequate feeding skills. They might not be able to
breastfeed and would require other methods of feeding such as spoon or gastric tube
feeding.
 These infants are prone to have significant illnesses in the first few weeks of life
 Preterm very low birth infants (VLBW) infants have higher fluid requirements in the
first few days of life due to excessive insensible water loss.

5.  Very low birth weight infants have low body stores at birth. Hence they require
supplementation of various nutrients.
 Because of the gut immaturity, they are more likely to experience feed
intolerance necessitating adequate monitoring and treatment.
The LBW infants categorized into two types :
1. Sick infants
` 2. Healthy infants.

6. Sick infants:
 This group constitutes infants with significant problems.
 These infants are usually started on intravenous (IV) fluids. Enteral feeds should
be initiated based on the infants’ gestation and clinical condition.
Healthy infants:
 Enteral feeding should be initiated immediately after birth in healthy LBW
infants.
 Appropriate feeding method determined by their gestation and oral feeding skills.

7. Choice of initial feeding method in LBW infants

8. How to decide the initial feeding method ?
 Traditionally, the initial feeding method in a LBW infant was decided
based on her birth weight. This is not an ideal way because the
feeding ability depends largely on gestation rather than the birth
weight.
 It is important to remember that not all infants born at a particular
gestation would have same feeding skills.

9. “NON- NUTRITIVE SUCKING”
 All stable LBW infants, irrespective of their initial feeding method should
be put on their mothers’ breast.
 The immature sucking observed in preterm infants born before 34 weeks
might not meet their daily fluid and nutritional requirements but helps in
rapid maturation of their feeding skills and also improves the milk
secretion in their mothers.

11. Spoon / Paladai feeding:
In LBW infants who are not able to feed directly from the breast this type of feeding
is used.
Intra- gastric tube feeding:
The disadvantages are
 In Naso- gastric feeding the tube increases the airway impedance and the work of
breathing in very preterm infants. Hence, oro-gastric tube feeding might be
preferable in pre-term infants

12. Paladai feeding

13.  In continuous intra- gastric feeding the major problem is that the lipids in the milk
tend to separate and stick to the syringe and tubes during continuous infusion
resulting in significant loss of energy and fat content.
All LBW infants, irrespective of their gestation and birth weight,
should ultimately be able to feed directly from the mothers’ breast. For preterm
LBW infants started on IV fluids/OG tube/ spoon feeding, the steps of progression
are

15. CHOICE OF MILK FOR LBW INFANTS:
All LBW infants, irrespective of their initial feeding method should receive ONLY
breast milk.
Expressed breast milk (EBM):
 All preterm infants mothers should feed their own milk to their infants.
 Expression should ideally be initiated within hours of delivery so that the infant
gets the benefits of feeding colostrum.
 Expressed breast milk can be stored for about 6 hours at room temperature and
for 24 hours in refrigerator.

16. Donor human milk:
 Donor human milk can be used for feeding a LBW infant. At present, only
a few centers in India have standardized human milk banking facilities.
 Hence, it is not a practical option in most of the settings across India.
In Special situations the Sick mothers / contradiction to breast feeding have
the options:

17. 1. Formula feeds:
a. Preterm formula – in VLBW infants and
b. Term formula – in infants weighing >1500g at birth.
2. Animal milk: E.g. undiluted cow’s milk.
Once the mother’s condition becomes stable (or the contra-indication
to breastfeeding no longer exists), these infants should be started on exclusive
breastfeeding.

18. Fluid requirement:
 The daily fluid requirement is determined based on the estimated insensible
water loss, other losses, and urine output.
 Extreme preterm infants need more fluids in the initial weeks of life because of
the high insensible water loss.
 We usually start fluids at 80 mL and 60 mL/kg/day for infants birth weights of
<1500g and 1500-2500g respectively.
 The usual daily increment would be about 15-20 mL/kg/day so that by the end
of first week 150 mL/kg/day is reached in both the categories. We usually reach a
maximum of 180mL/kg/day by day 14.

19. Supplementation of infants of weight 1500-2500g:
• These infants are more likely to be born at term or near term gestation (>34
weeks). Hence, they do not require multi nutrient supplementation or fortification
of breast milk.
• Vitamin D and iron might still have to be supplemented in them.
• AAP recommends vitamin D (200 IU) is started at 2 weeks and iron (2
mg/kg/day) at 2 months of life; both are continued till 1 year of age.

20. Supplementation of VLBW infants:
• These infants who are usually born before 32-34 weeks gestation have
inadequate body stores of most of the nutrients.
• Expressed breast milk has inadequate amounts of protein, energy, calcium,
phosphorus, trace elements (iron, zinc) and vitamins (D, E & K) that are
unable to meet their daily recommended intakes.
• Hence VLBW infants need to supplement till they reach normal term gestation
(40 weeks)

21. Multi-nutrient supplementation can be ensured by one of the following
methods:
1. Supplementing individual nutrients – E.g., calcium, phosphorus, vitamins,
etc.
2. By fortification of expressed breast milk:
a. Fortification with human milk fortifiers (HMF)
b. Fortification with preterm formula

22. Growth monitoring of LBW infants:
• Regular growth monitoring helps in assessing the nutritional status and adequacy
of feeding, it also identifies LBW infants with inadequate weight gain.
• All LBW infants should be weighed daily till the time of discharge from the
hospital. Other anthropometric parameters such as length and head circumference
should be recorded weekly.
LBW infants should be discharged after:
• They reach 34 weeks gestation and or above 1400g .
• They show consistent weight gain for at least 3 consecutive days.

23. Use of Growth charts:
It is a simple but effective way to monitor the growth. The plotting
of measurements in GC helps to compare the individual infants growth with
reference standards.
 It helps in early identification of growth faltering in the infants.
Two types of growth charts:
1. Intrauterine
2. Postnatal.
Most commonly used for growth monitoring of preterm VLBW infants are:
Wright’s and Ehrenkranz’ charts.

24.  The postnatal growth chart is preferred because it is a more realistic
representation of the true postnatal growth (than an intrauterine growth chart)
and also shows the initial weight loss that occurs in the first two weeks of life.
 Once the preterm LBW infants reach 40 weeks PMA, WHO growth charts should
be used for growth monitoring.
Causes of inadequate weight gain:
1.Inadequate intake
Breastfed infants:
 Incorrect feeding method (improper positioning/attachment)

25. Less frequent breastfeeding, not feeding in the night hours
Prematurely removing the baby from the breast (before the infant completes feeds)
Infants on spoon feeds:
Incorrect method of feeding (e.g. excess spilling)
Incorrect measurement/calculation
Infrequent feeding
Not fortifying the milk in VLBW infants
Energy expenditure in infants who have difficulty in accepting spoon feeds

26. 2. Increased demands
Illnesses such as hypothermia/cold stress*, bronchopulmonary dysplasia
Medications such as corticosteroids
3. Underlying disease / pathological conditions
Anemia, hyponatremia, late metabolic acidosis
Late onset sepsis
Feed intolerance.

28. Conclusion:
Optimal feeding of LBW infants is important for the immediate
survival as well as for subsequent growth.
 Compared to the normal birth weight infants, pre-term birth infants have vastly
different feeding abilities and nutritional requirements.
 They are also prone to develop feed intolerance in the immediate postnatal period.
 It is important for all health care providers caring for such infants to be well
versant with the necessary skills required for feeding them.
