While often thought to be late, first babies are actually slightly more likely to be born early (preterm, before 37 weeks) than later babies, though the average first birth is still around the due date or just slightly after (40 weeks, 5 days), with many factors like genetics influencing timing.
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.
Women who give birth to their first child even a couple of weeks early are up to three times more likely to deliver their next baby prematurely, new research suggests. "The magnitude of the increased risk surprised us -- it really is a potent factor," said senior study author Laura Jelliffe-Pawlowski.
If you have any of these signs or symptoms before your 37th week of pregnancy, you may be experiencing preterm labor: Change in your vaginal discharge (watery, mucus or bloody) or more vaginal discharge than usual. Pressure in your pelvis or lower belly, like your baby is pushing down. Constant low, dull backache.
If "early" means preterm – before 37 weeks of pregnancy – first babies are more likely to be early. Based on live births recorded in the National Survey of Family Growth, about 12% of first babies are born preterm, compared to 10% of other babies.
In support of the widely held understanding that first babies are more likely to be born “late,” we found that deliveries go beyond 41 weeks' gestation 1.53 times more frequently among mothers with a first-time delivery compared to those who have previously delivered, confirming anecdotal wisdom.
For most women, labor begins sometime between week 37 and week 42 of pregnancy. Labor that occurs before 37 weeks of pregnancy is considered premature, or preterm.
The "5-5-5 rule" in a labor/postpartum context is a guideline for new mothers to prioritize rest and recovery in the first 15 days after childbirth, suggesting 5 days in bed, followed by 5 days on the bed (minimal movement), and then 5 days near the bed (gentle movement around the home). This promotes healing, bonding, and reduces stress, though it's a flexible guide, not a strict mandate, with some experts suggesting early movement can help prevent blood clots, making a modified approach ideal.
When your baby drops, it's a sign that your body is gearing up for labor. For first-time moms, this often happens between 36 and 40 weeks, while for those who've been through it before, it might not happen until labor is closer.
Three key signs that labor is approaching soon are regular contractions, losing your "bloody show" (mucus plug), and your waters breaking, often accompanied by lower backache, baby dropping, or a sudden urge to clean (nesting). These signals show your body is preparing for birth, with contractions becoming stronger and closer together as labor progresses.
Average baby weights
The average weight of a baby born at 37 to 40 weeks ranges from 5 lb 8 oz to 8 lb 13 oz. This equates to 2.5 to 4 kg. At delivery, experts consider a low birth weight to be less than 5 lb 8 oz, or 2.5 kg. It is common for babies to lose around 10% of their weight during the first week after birth.
First-time mothers are most likely to give birth in the 39th or 40th week. For twins, spontaneous births typically occur around weeks 36 and 37, and few pregnancies go beyond 38 weeks, due to medical considerations. “Full term” is now defined as 39 to 40 weeks, while 37 to 38 weeks is called “early term.”
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.
Health care providers use methods like the last menstrual period, ovulation dates, and ultrasounds to estimate due dates. Factors like age, carrying multiples, or having certain health conditions can influence whether a baby arrives early or late.
In most cases, your labor will begin only when both your body and your baby are ready.
Prioritize Rest
I always recommend that my clients aim to be “down” more than “up” during the first two weeks. You may have heard of the 5-5-5 rule for postpartum care, which recommends 5 days in bed, 5 days on the bed, and 5 days around the bed.
Maintaining a healthy pregnancy is not hard when you know how to do it! The three golden rules are to always listen to your doctor's advice, eat healthy, and stay active. Remember, don't focus only on your baby's growth because ultimately keeping yourself healthy is the first step to keeping your baby healthy!
The 2-hour rule for babies means they shouldn't stay in a car seat (or travel system seat) for more than two hours at a time, whether in or out of the car, because the semi-upright position can strain their developing spine and restrict their breathing, increasing the risk of low oxygen levels, especially for newborns and preemies. For long journeys, parents should take breaks every two hours to take the baby out, allow them to lie flat for a while, stretch, and feed, ensuring they get proper head/neck support and circulation.
Silent labor, also known as a painless or unrecognized labor, occurs when contractions are mild or not easily felt. Some individuals may only realize they are in labor when they reach active labor or are close to delivery.
Early Signs of Labour
To break your water, your healthcare provider inserts the amnihook through your vagina. Once they find the bag of water or amniotic sac, they scratch or tear a hole in it to allow the fluid to escape.
Pushing your baby out
You may not feel the urge to push immediately. If you have had an epidural, you may not feel an urge to push at all. If you're having your 1st baby, this pushing stage should last no longer than 3 hours. If you've had a baby before, it should take no more than 2 hours.
How big is your baby at 32 weeks pregnant? Your baby is a little over 16 inches (40.6 cm) long and weighs between 4 and 4 ½ pounds (1.8 to 2 kg).
Early signs of labour are typically felt between 37 and 42 weeks of pregnancy. Early signs of labour include cramps, a 'show' or your waters breaking. A 'show' is bloodstained vaginal discharge. Braxton Hicks contractions are not true labour contractions.
