You probably know someone whose baby was born before 37 weeks. Her baby may have looked or even acted like a full-term baby, but it’s not. There’s a group of premature babies that parents need to be particularly aware of, and that’s babies born between 34 gestational weeks and 36 weeks and 6 days gestational age - late preterm infants.

Although late preterm infants are usually significantly larger than very premature newborns, they are still premature and have their own, unique health considerations.

Did you know that babies born just three to six weeks early are at greater risk for potentially serious health problems than full-term newborns? If you’re at risk for giving birth to a baby in this preterm window, or have just given birth to one, there are five critical things you need to know and watch for:

Feeding

Late preterm infants tend to feed slower and may need to be fed more of ten than full-term babies. As a late preterm infant, your baby may not be able to take in as much breast milk or formula at each feeding.

It’s essential that you feed your baby at least every 2 to 4 hours for the first several days to help prevent jaundice. If your baby refuses feedings, even for less than a day, contact your healthcare provider right away. Some late preterm infants have problems starting or maintaining breastfeeding; if so, ask for support from your care provider or a lactation consultant.

Sleeping

Your preemie baby may be sleepier than full-term infants and may sleep through needed feedings. You need to wake your baby to feed every 3 to 4 hours. And always put your baby on his back to sleep.

Breathing

Late preterm infants can be at greater risk for respiratory distress. If your baby seems to be having trouble breathing, call your healthcare provider or his pediatrician immediately or dial 911.

Temperature

Your late preterm baby has less body fat than full-term infants and may struggle to regulate his body temperature. Keep him away from drafts. And keep your house just warm enough to maintain a normal body temperature and avoid overheated rooms. A good rule of thumb is to dress your baby in one more layer than you’re wearing.

Jaundice and Infections

Your premature baby is also more likely to develop jaundice, a symptom of a condition called hyperbilirubinemia, that can lead to severe nervous system damage if not identified and treated early. Make sure your baby is screened for jaundice prior to leaving the hospital. All babies should be seen by their nurse practitioner or pediatrician within 24 to 48 hours of discharge; immediately if their skin becomes yellow or if they’re not feeding well.
