You are carrying 23 wk pregnancy
and confused with breast feeding to baby.
Breast feeding is ideal & mandatory and universally acceptable for at least 6 months of age of the baby to give proper nutrition, protective measures from several infection,mother & baby close attachment with emotional bonding, prevent hypothermia
and obviously better growth & development with better IQ.
There is no substitute of Exclusive Breast Feeding (EBF). Nothing to be given orally during EBF for first 6 months. There are several supplements available in market to increase breast milk if you think that milk is not sufficient. So don't waste your time regarding unhealthy words.
Do periodic check up with Iron/Calcium supplements
and monitor baby development by USG.
