Aim: To compare the success of singleton and twin preterm infants in establishing and maintaining breast feeding, and to evaluate the effectiveness of current programmes to promote breast feeding.
Methods: All infants less than 37 weeks gestation discharged in one month from the special care baby unit at National Womens Hospital were studied. Data on the infants and their in hospital course was recorded from the neonatal records. The mothers were contacted by telephone 3 to 4 months after discharge, to elicit the subsequent breast feeding rates.
Results: Thirty of 33 preterm infants (29 to 36 weeks gestation) were breast fed at discharge from hospital: 93% of singletons, and 89% of twins. The twins were older and heavier at discharge (p < 0.004) due to their longer hospital stays (28.4 vs 16.3 days, p < 0.05). All but 2 infants progressed to exclusive breast feeding. There was a similar rate of decline in the rates of breast feeding in singletons and twins to 68% at 8-12 weeks and 49% at 12-16 weeks after birth.
Conclusions: Preterm twins can breast feed as successfully as preterm singleton infants; as with sufficient assistance and encouragement, their rates of breast feeding were comparable to those of term infants. Although the resources of this hospital do not allow preterm infants to become fully breast fed before discharge, the current programme at National Womens Hospital is effective in establishing successful breast feeding in these high risk infants.
