Hypothesis -Infants born preterm started on complementary feeding at 6 months corrected age have better outcome in terms  of growth when compared to initiation of complementary feeding at 6 months chronological age .

Consent-

Parents or legally acceptable representative (LAR) of newborns meeting eligibility criteria will approached for informed consent. An information sheet providing the details of the study will be provided to the parents/LAR Parents are free not to participate, or to withdraw their child from the study at any point of time and no coercion will be involved.

 Enrollment-Babies born between 26-34 wks are discharged from department of neonatology ,these neonates discharged from our hospital will be asked to follow up in High risk clinic .At 6 months of chronological age the baby would be  enrolled & randomisation into group A (Introduction of complementary feed at 6 months corrected age)or group B(Introduction of complementary feed at 6 months chronological age)  is done .

IYCF counselling at enrolment will be  done in all neonates in our  study. All twins & triplets to be enrolled in same group.

Primary objective:

To compare the effects of introduction of complementary feeding in 6 months corrected age vs 6 months chronological age in anthropometry.

a)      Weight for age (grams)

b)      Lt for age, (cm)

c)      Weight for Length,

d)      HC for age,(cm)

e)      MUAC including z scores,

f)       triceps skin fold thickness (mm)

Secondary objectives:

1.      Mortality rate, & Duration of hospital stay at  3 month & 6 month of starting of complementary feeding  .

2.      Recurrence of infection requiring additional hospitalization, at 3 month & 6 month of starting of complementary feed.

3.      Iron status, at the starting of complementary feeding & 6 months of starting of complementary feeding

4.      Calcium homeostasis (ca+2,po 4 ,alkaline phosphatase ),at the starting of complementary  feeding & 6 months of starting of complementary feeding.

5.      Hormonal assay (leptin ,cortisol  ),at 6 months of starting of complementary feeding.

6.      BP at 6 months of starting of complementary feeding

7.        Neurodevelopment  at 6 months of starting of complementary feeding,
