Hi everyone As we all know, NEC is our night mare in NICU. Especially in extreme preterm, we are facing a significant problem when we ran short of breast milk where we don't have breast milk bank. Since 2017 I used to start amino acid based formula with extreme preterm till reach full feed, then start shifting to regular preterm formula gradually. This led to reduction of NEC rate significantly but no study has been done so far. Few other consultants in scattered tertiary centers are following the same approach. Can you please tell us your input.?
