A premature baby needs to be able to maintain their body temperature in an open crib before they can go home. 1 When your baby is able to do this will depend more on their weight than their gestational age. In general, preemies can maintain their own body temperature once they weigh about 4 pounds.
Some hospitals have a rule on how much the baby must weigh before going home, but this is becoming less common. In general, babies are at least 4 pounds (2 kilograms) before they are ready to come out of the incubator.
Nearly all low birthweight babies need specialized care in the Neonatal Intensive Care Unit (NICU) until they gain weight and are well enough to go home. Fortunately, there is a 95 percent chance of survival for babies weighing between 3 pounds, 5 ounces, and 5 pounds, 8 ounces.
Satisfactory weight gain during the five to seven day period preceding discharge and weight ≥1800 g at discharge.
Healthy, full-term babies (at least 37 weeks gestation) can usually go home from the hospital sometime between 24 and 48 hours after birth.
This is because before 4 months your baby will still be establishing breastfeeding and building a connection between both parents, so they're a little too young to be away from you. After 9 months, most babies will develop separation anxiety and will likely have a hard time being away from their parents.
The earliest a baby can go home is 35 weeks gestation, but I usually advise parents to expect to go home close to their due date.
Preemie babies may gain weight more slowly than full-term infants, but they often catch up in size around age 2.
The average full term baby's birthweight is around 7 pounds. The weight of a premature infant varies greatly and depends on the baby's gestational age at birth. A premature baby can weigh anywhere from one pound to 5 pounds. It can be a bit overwhelming to see such a tiny baby, especially for the first time.
Many babies born before 32 weeks, and those weighing 2.5 kg or less, may need help breathing. They will usually be cared for in a neonatal intensive care unit (NICU) until they have developed enough to survive on their own. Babies born between 32 and 37 weeks may need care in a special care nursery (SCN).
Newborns come in a range of healthy sizes. Most babies born between 37 and 40 weeks weigh somewhere between 5 pounds, 8 ounces (2,500 grams) and 8 pounds, 13 ounces (4,000 grams). Newborns who are lighter or heavier than the average baby are usually fine.
Kamath's team found that 9.3 percent of the c-section babies were admitted to the NICU, but just 4.9 percent of the vaginally delivered babies were. And while 41.5 percent of the c-section babies required oxygen in the delivery room, 23.2 percent of the vaginally delivered babies did.
For example, at 48 hours, the average infant born vaginally has lost 7 percent of body weight, and 5 percent of infants have lost more than 10 percent. For at least some infants, weight loss continues through 72 hours.
If your baby weighs less than 2.5kg at birth, their head may appear to be a lot bigger than the rest of their body. They may look thin with little body fat. Babies of low birth weight or those who are born prematurely, may need to be admitted to the neonatal intensive care unit (NICU) or special care nursery (SCN).
27 to 28 Weeks
However, 27- and 28-weekers still require a lot of medical care and can be expected to stay in the NICU for months.
Healthy breastfed infants typically put on weight more slowly than formula-fed infants in the first year of life. Formula-fed infants typically gain weight more quickly after about 3 months of age. Differences in weight patterns continue even after complimentary foods are introduced.
The average weight for full-term babies (born between 37 and 41 weeks gestation) is about 7 pounds (3.2 kg). In general, small babies and very large babies are more likely to have problems. Newborn babies may lose as much as 10% of their birth weight.
Although every baby is different, in most cases babies born before 36 weeks of gestation require a minimum of one day of observation in the NICU before they are transferred to the postpartum floor to stay with you. All babies born before 35 weeks gestation will need a longer observation period in the NICU.
Early term: Your baby is born between 37 weeks, 0 days and 38 weeks, 6 days. Full term: Your baby is born between 39 weeks, 0 days and 40 weeks, 6 days. Late term: Your baby is born between 41 weeks, 0 days and 41 weeks, 6 days. Postterm: Your baby is born after 42 weeks, 0 days.
SIDS peaks between 1 and 4 months of age, and 90% of the cases take place in the first 6 months of life.
The researchers found that 50% of all women giving birth for the first time gave birth by 40 weeks and 5 days, while 75% gave birth by 41 weeks and 2 days. Meanwhile, 50% of all women who had given birth at least once before gave birth by 40 weeks and 3 days, while 75% gave birth by 41 weeks.
You may not be able to spend as much time as you'd like with your baby. If you don't live close to the NICU, ask the staff about free or low-cost hotels in the area for NICU parents. And some NICUs have rooms for parents to sleep in.
Depending on your baby's health, you might be able to hold your little one even if he or she is on a ventilator or has an IV. If the doctors feel that would be too much, you can still hold your baby's hand, stroke his or her head, and talk and sing to him or her. A gentle touch will be the most reassuring.
Health Outcomes for 34-Week Old Preemies
But, it's important to know that 34-week-old infants will probably need to stay in the hospital for one to two weeks in the Newborn Intensive Care Unit. In long-term follow-up, these infants do very well and usually are as healthy as non-preemies.
