other factors include :
- Size of parents. Big and tall parents may have larger-than-average newborns; short and petite parents may have smaller-than-average newborns.
- Multiple births. If you have twins, triplets, or more, you can count on your babies being a bit small. Multiples have to share their growing space in the uterus, and they’re often born early, which leads to small size at birth.
- Birth order. First babies are sometimes smaller than brothers or sisters born later.
- Gender. Girls tend to be smaller, boys larger, but the differences are slight at birth.
- Mom’s health during pregnancy. Things that can lead to a lower birth weight include a mother with high blood pressure or heart problems; or one who used cigarettes, alcohol, or illegal drugs during the pregnancy. If the mother has diabetes or is obese, the baby may have a higher birth weight.
- Nutrition during pregnancy. Good nutrition is vital for a baby’s growth — before and after birth. A poor diet during pregnancy can affect how much a newborn weighs and how the infant grows. Gaining a lot of weight can make a baby more likely to be born bigger than average.
- Baby’s health. Medical problems, including some birth defects and some infections during the pregnancy, can affect a child’s birth weight and later growth.

What About Preemies?
previous babies broadly are smaller and weigh less than other newborns. A premature baby ‘s weight will largely depend on how early he or she was born. The time an baby missed being in the uterus was growing time, so the baby has to do that growing after give birth .
many pre-term babies are classified as having “ low birth weight “ or “ very low birth weight. ” In medical terms :
- Low birth weight means a baby weighs less than 5 pounds, 8 ounces (2,500 grams) at birth. That’s the case for about 1 in every 12 babies in the United States, so it’s quite common.
- Very low birth weight means a baby weighs less than 3 pounds, 5 ounces (1,500 grams).
Most babies with low parturition weight or identical broken give birth weight were born prematurely .
premature babies get particular checkup care right off after they ‘re born. A specialist called a neonatologist may help care for them. many preemies spend time in the neonatal intensifier care unit of measurement ( NICU ) while they get aesculapian worry .
Is Bigger Better?
A baby with chubby cheeks and dimpled thighs once was many people ‘s picture of a healthy newborn. But a baby born a lot larger than average may have special checkup problems that need attention.
Some identical big babies — specially those born to mothers with diabetes, including gestational diabetes — may have problems for a few days keeping rake sugar levels up. They might need extra feedings or even IV ( given into a vein )

Will My Baby Lose Weight?
to keep those levels from falling besides moo. Yes, at first base. Babies are born with some supernumerary fluent, so it ‘s normal for them to drop a few ounces when they lose that fluent in the first few days of life.

During their first calendar month, most newborns gain burden at a rate of about 1 ounce ( 30 grams ) per day. They broadly grow in altitude about 1 to 1½ inches ( 2.54 to 3.81 centimeters ) during the inaugural month. many newborns go through a period of rapid growth when they are 7 to 10 days old and again at 3 and 6 weeks .

Should I Be Concerned?
Newborns are then small, and it can be hard to know if your baby is gaining weight the manner he or she should. You may worry that your baby has lost besides much system of weights in the first few days or is n’t taking adequate front milk or formula. If thus, lecture to your doctor, who may ask you about :
- How many feedings a day your baby gets. A breastfed baby may feed about 8 or more times in a 24-hour period; formula-fed babies usually eat less often, perhaps every 3 to 4 hours. A lactation (breastfeeding) counselor can make suggestions to increase comfort and improve technique, if a mom needs extra help.
- How much your baby eats at each feeding. A baby generally nurses for at least 10 minutes, should be heard to swallow after 3 or 4 sucks, and should seem satisfied when done. At this age, formula-fed babies may drink up to 3 to 4 ounces (90 to 120 milliliters) at a time.
- How often your baby pees. A breastfed baby may have only 1 or 2 wet diapers a day until the mother’s milk comes in. Expect about 6 wet diapers by 3 to 5 days of age for all babies. After that, babies should have at least 6 to 8 wet diapers a day.
- How many bowel movements your baby has each day, and what they’re like. Newborns may have only one poopy diaper a day at first. Poop is dark and tarry the first few days, then becomes soft or loose and greenish-yellow by about 3 to 4 days. Newborns usually have several poopy diapers a day if breastfed and fewer if formula-fed.
