Correcting 1~2 months How can I tell if my baby needs to add breast milk fortification or preemie formula?

To determine if you need to add breast milk fortification or preterm formula, it depends on the baby’s weight. If it does not reach the 25th percentile, you should continue to add breast milk fortification or preterm formula, and if you have mother’s milk, half of the mother’s milk should be fortified with breast milk, and if there is not enough breast milk, you can use half of the breast milk and half of the post-discharge preterm formula, and you can keep eating until your weight reaches the 25th percentile or above.
