In 2018, WHO estimated that 10.5% of babies in Malawi are born with low birth weight of whom the majority are premature; therefore all health care providers must be familiar with the care of this group of infants.
A neonate who weighs less than 2500g is a low birth weight baby. Nearly 75% of neonatal deaths occur among low birth weight neonates. Even after recovering from neonatal complications, some LBW babies remain more prone to malnutrition, recurrent infections, and neurodevelopmental handicaps.
Infants with LBW may be small due to either prematurity or intra-uterine growth retardation (IUGR). IUGR results in a baby who is small for gestational age (SGA). It is helpful to try and decide if the aby is premature or SGA, as the management is slightly different. SGA babies are symmetrically small.
Remember, they could also be both premature and SGA. There are maturity charts or scoring systems that can help to decide the gestation age of a baby. .

Often the gestational age of newborns is not clear and approximations have to be made. The most accurate way to do this is to use a maturity chart. Approximate gestational age can be estimated by adding the scores of the following features shown below [Parkin Score (2)].
Approximate Gestational Age Based on Physical Characteristics (Parkin Score
0 | 1 | 2 | 3 | 4 | |
Skin Texture | Very thin | Thin and smooth | Smooth,medium thickness. Rash and superficial peeling | Slight thickening, superficial cracking and peeling, especially of hands and feet | Thick, superficial or deep cracking |
Skin Colour | Dark red | Uniformly pink | Pale pink | Pale, nowhere really pink except ear, lips, palms, soles | |
Ear Firmness | Soft pinna, no springing back into position spontaneously | Soft pinna along the edge, slow spontaneous return into position | Thin cartilage in pinna edge, readily springs back into position | Firm pinna with definite cartilage | |

The delivery of an expected LBW baby should be in hospital. Premature labour as well as intrauterine growthretardation is anindication to refer a pregnant woman to hospital before the baby is born (in-utero transfer).
The mother and the family under the supervision of a health care worker can manage an otherwise healthy LBW newborn with a birth weight of 1500 grams or above at home.
Infants below this weight are at risk of hypothermia, feeding problems, apnoea, respiratory distress syndrome, and necrotizing enterocolitis. The risks associated with keeping the child in hospital (e.g., hospital-acquired infections) should be balanced against the potential benefit of better monitoring and care, such as reviewing the infants at least twice a day to assess feeding ability, fluid intake or the presence of any danger signs. The risk of hospital-acquired infection can be reduced by keeping the mother and baby together and using Kangaroo Mother Care.
The definition of Continuous Kangaroo Mother Care (KMC) is care of a preterm infant carried skin-to-skin with the mother. Its key features include early, continuous, and prolonged skin-toskin contact between the mother and the baby, and exclusive breastfeeding (ideally) or feeding with breast milk. Mortality, hypothermia, rates of infection, and readmission are lower in neonates nursed in continuous KMC when compared with conventional care. Weight gain will be faster with KMC compared to conventional care. All newborns weighing 2000 g or less at birth should be provided with as much continuous KMC as possible.
Intermittent KMC is the practice of skin-to-skin care alternated with the use of a warming crib, radiant warmer, or an incubator care for the baby. Intermittent KMC is associated with reduced rates of hypothermia and infection compared to conventional care.
In Malawi, there are three categories of KMC:
If neither continuous nor intermittent KMC is possible then an overhead radiant warmer, incubator, or warming crib may be used to keep the baby warm. The room where a LBW baby is nursed should be kept warm (25oC). The baby should wear a hat to cover the head. Wet clothing should be changed frequently to keep the baby warm and dry. Regular monitoring of axillary temperature should be done.
Key Facts for Providers and Mothers/Guardians: Skin-to-skin contact (Kangaroo Mother Care) |
|
---|---|
If there are no signs of distress, a mother can provide a warm environment with
Let the baby suckle at the breast as often as s/he wants, but at least every 2 hours. Mother should sleep propped up so that the baby stays upright. If environmental temperature is low add a blanket to mother’s wrap. When mother wants to bathe or rest, ask the father or another family member to ‘Kangaroo’ the baby or wrap the infant in several layers of warm clothing, covered with blankets, and keep in a warm place. If the feet of the baby feel cold, s/he requires extra warmth. |
Breast milk is the preferred milk because it has a high electrolyte and protein content necessary for rapid growth of the baby. The antibodies and other anti-infective factors in mother’s milk are very necessary for the survival of a preterm baby.
Weight | Ideal Feeding Regime |
---|---|
<1500 g or < 32 weeks | Feed every two hours |
>1500 g or > 32 weeks | Feed every three hours |
Key Facts for Providers and Mothers/Guardians: Feeding LBW/Premature Infants |
|
---|---|
Feeding should be scheduled because preterm infants rarely demand feeds. Work out a schedule with the mother for her to follow. LBW babies may take longer on the breast. |
Birth weight, gestation, presence or absence of sickness, and individual feeding efforts of the baby determine the decision as to how a LBW neonate should receive fluids and nutrition. The gestational age is one of the most important determinants, as coordinated sucking and swallowing does not develop until about 34 week’s gestation.
Likely route of feeding according to age:
Birth weight/ Gestational age |
<1500 grams / <32 weeks | 1500-1800 grams / 32-34 weeks | >1800-2500 grams / >34 weeks |
---|---|---|---|
1-3 days of life | Tube feeds | Tube feeds or cup | Breastfeed, if unsatisfactory use cup |
3 days-3 weeks of life | Tube or cup | Breastfeed, if unsatisfactory use cup | Breastfeed |
Those unable to feed directly on the breast, but who are clinically stable, can be given expressed breast milk (EBM) by oro-gastric tube or cup feeds. The mother should express her own milk into a clean container. In order to promote lactation, and enable the baby to learn to suck, all babies more than 1500 grams and 32 weeks of gestation should be put on the breast for 5-10 minutes before cup or tube feeding.
Is the baby able to breastfeed effectively?
When offered the breast, the baby roots, attaches well and sucks effectively. S/he is able to suck long enough to satisfy needs.
Is the baby able to accept feeds by alternative methods?
When offered cup feeds, the baby opens the mouth, takes milk, and swallows without
coughing or spluttering.
S/he is able to take an adequate quantity to satisfy needs.
Is the baby getting enough breastmilk?
The best way to find out is to see how fast the baby grows over a few days. Babies need different amounts of breast milk to grow at the same rate. Too fast growth and too slow growth can cause health problems. The key measure of optimal feeding is the weight pattern of the baby. The ideal weight gain is similar to the average weight that a foetus gains in the uterus, about 15-20g/kg/day.
A Preterm LBW | Baby may lose up to 15% cumulative weight during the first week
of life. Observe for causes of inadequate feeding:

---|---|
SGA Babies | Should not have any appreciable weight loss at all and they should start gaining weight early. |
If nutrition supply of the baby is found to be inadequate due to reduced milk supply of the mother, there are several ways to increase the milk production:
Maintenance feeds by gastric tube or by cup – see wall charts.
Key Facts for Providers and Mothers/Guardians: Breast Milk Expression |
|
---|---|
It is useful for all mothers to know how to express their milk. Expression of
breast milk is required in the following situations:
Technique of expression – teach mother to:
|
Insertion of a nasogastric tube: The catheter is measured from the tip of the nose to the ear lobe and then to the midpoint between the xiphoid and umbilicus. Mark the position on the tube with a piece of tape. This length of the tube should be inserted through the nose. For tube feeding, use French size 5 or 6 nasogastric tubes.
Oro-gastric tube feeding (OG tube) and naso-gastric tube feeding (NGT)
Insertion of an oro-gastric tube: measure the distance between angle of mouth to earlobe, and then to the midpoint between the xiphoid and umbilicus. Mark the position on the tube with a piece of tape. This is the length of tube that is inserted.
During nasogastric or oro-gastric insertion, the head is slightly raised and a wet (not lubricated) catheter is gently passed through the nose (nasogastric) or mouth (oro-gastric) down through the oesophagus to the stomach. Its position is verified by aspirating the gastric contents and auscultating over the epigastric region. Injecting air into the tube can be dangerous.
At the time of feeding, the outer end of the tube is attached to a 10/20ml syringe (without plunger) and milk is allowed to trickle by gravity. There is no need to burp a tube-fed baby.
The nasogastric or oro-gastric tube should be left in situ for up to three (3) days.
While pulling out a feeding tube, it must be kept pinched and pulled out gently.
Tube feeding may be risky in very small babies. They have small stomach capacity and the gut may not be ready to tolerate feeds. Stasis may also result from paralytic ileus due to several conditions. Thus, tube-fed babies are candidates for regurgitation and aspiration. It is important therefore to take precautions.
Before the next feed, aspirate the stomach, if the aspirate is more than 25 percent of the last feed, the baby should be evaluated for any illness. The feeds may have to be decreased in volume or stopped and replaced with IV fluids.
Baby should be awake and held sitting semi-upright on caregiver’s lap. Put a small cloth on the front of chest to catch drips of milk.
Document the time and amount of feed that the baby received.
Supplement | Route | Timing and duration |
Vitamin K National Guidelines |
0.5 mg in preterm neonates IM 1 mg in term neonates IM | Birth |
Multivitamin
preparation if available |
0.3-0.6 ml (5-10 drops) /day (which usually provides vitamin A of 1000 iu/day and vitamin D 400 iu/day) | When taking full feeds until 6 months |
Iron if available |
Start iron supplements at 2 weeks of age
if tolerating full enteral feeds at a dosage
of 2–4 mg/kg per day until 6 months of
age. Syrup usually contains 50 mg iron in 5 mls or 10 mg per ml so a 2 kg baby will get 0.5 mls. |
