How long does it take for a 29-week preterm baby to catch up with a normal baby is uncertain, depending on how well the preterm baby is fed and whether he or she suffers from some illnesses. If breastfeeding can be strengthened and care taken, the baby can usually catch up in about a year, but there are big individual variations. Preterm babies born at 29 weeks are very small and need to be carefully cared for in the neonatal unit. After birth, if breastfeeding can be given and if the baby has no other organ problems after birth, most of them can catch up with the growth and development of normal babies in about one year. However, if the newborn baby is born with some cardiopulmonary abnormalities and organ pathologies that need to be treated, the time to catch up with a normal baby will be longer. In the process of growth and development, preterm birth weight light, resistance to decline, if often sick, will also affect his growth and development, can not catch up with normal babies, so the above still exists a relatively large individual differences, preterm babies should be discharged from the hospital should also be regular pediatrician clinic to ensure good health.
