Keep in mind that more than half of twins are born prematurely, and while they may sleep more overall than full-term infants (up to 22 hours a day), they do so for shorter periods of time. If your babies are eating every four hours, let them snooze — and when they're ready for sleep training, here's how to do it.
In fact, once twins get the hang of sleep, they might even outshine non-twins in the zzz's department. As obstetrician-gynecologist Dr. Manju Monga tells WebMD, “Young twins are easier to raise, have each other to play with, and sleep better than singletons once they turn 2.”
This is called co-bedding and is perfectly safe. In fact, putting twins in the same cot can help them regulate their body temperatures and sleep cycles, and can soothe them and their twin.
Because multiples often weigh less than single babies, it may take longer for your babies to sleep through the night. While there's no research that consistently proves this, anecdotal evidence shows that identical twins tend to sleep through the night around the same age.
At three months:
The three-month stage marks the end of the “fourth trimester” and your twins can better adapt to life outside the womb. For one thing, they'll sleep in longer stretches of about three- to four-hour chunks.
People over 30, and particularly those over age 35, are more likely to conceive twins. 4 This is because the level of follicle-stimulating hormone (FSH) rises as birthing parents get older. FSH is responsible for the development of eggs in the ovaries before they are released.
The reality is that raising multiples is hard. You have double or triple the feeding, diapering, and laundry and, as a result, less time to spend cuddling and getting to know each baby. To be sure, there will be days when you feel as if you're walking up a down escalator.
The longest interval between the birth of twins is 90 days, in the case of Molly and Benjamin West, dizygotic (fraternal) twins born in Baltimore, Maryland, USA to parents Lesa and David West (all USA) on 1 January and 30 March 1996.
“Having twins is not twice as hard—it's exponentially more difficult,” says Natalie Diaz, author of What To Do When You're Having Two and CEO of Twiniversity, a global support network for parents of twins.
Measures included actigraphy, sleep diaries, and standardized instruments for fatigue, sleep quality, and depression. According to the results, by the time the twins reached full-term, mothers were sleeping an average of 5.4 hours in a 24-hour period, with over 70 percent reporting less than six hours of sleep.
Maureen Healy, an expert on sensitive children and author of Growing Happy Kids, tells Romper that twins have a bond that is oftentimes unexplainable and are closer than typical siblings — whether they're fraternal or identical. Healy says a lot of experts believe it's because this closeness is rooted in genetics.
Identical twins share a particularly intense bond. They are the result of one fertilized egg splitting into two, giving them identical DNA. (Fraternal twins are the result of two separate, genetically different fertilized eggs.) As a result, identical twins are as close as two people can be.
There's no compelling need for twins to have separate bedrooms, nor do they automatically do best if they're in the same room, especially when they're very young. However, keep in mind that, after about 6 months of age, infants begin to get used to a certain environment, including the presence of a sibling.
For women born 1870-1899, moms of twins averaged reproductive spans of 14 years 11 months versus 14 years for singleton moms. Both results were statistically significant. Moms of twins also were older at the time of their last birth.
Twins and other multiple-birth individuals can suffer from much deeper and troubling loneliness than single-born individuals. Separation anxiety, which often begins at birth, is the underlying cause of loneliness for twins.
Severe Fatigue
Extreme fatigue is the most commonly reported complaint during pregnancy with multiples. Sleepiness, lethargy, and exhaustion during the first trimester can be enhanced because the body is working overtime to nurture more than one baby.
Being a twin has its benefits—tricking people, having a lifelong companion, sharing clothes—but it also has downsides. Many twins struggle to cultivate their own identities, while being so similar to one another. And that struggle lasts a lifetime, according to a recent study.
While 40 weeks is the full gestation period of the average pregnancy, most twin pregnancies are delivered at approximately 36 weeks (range 32-38 weeks depending on the type of twin pregnancy).
The interval between vaginal delivery of the first and second twins (mean, 21 minutes, range, one to 134 minutes) was 15 minutes or less in 70 (61%) cases and more than 15 minutes in 45 (39%) cases.
Multiples are generally born only a few minutes apart. If delivered by cesarian section, the interval between births is usually only a minute, maybe two. The interval is generally longer for vaginal deliveries, ranging from a few minutes to more than an hour.
In a typical identical twin pregnancy, an egg splits during its first week after fertilization. But in a mirror twin pregnancy, the egg splits 7 to 12 days after it's been fertilized — long enough for the egg to have developed a right and a left side.
Having two babies at a time is associated with a longer life, according to a new study. But that's not because doubling up on dirty diapers increases life span; instead, moms of twins are physically stronger in the first place.
Physically recovering from a multiple birth, whether it was vaginal or via C-section, is much like recovering from a singleton birth — only more so. Indeed, the postpartum period can be worse with twins or triplets, as everything you experience will feel just a little bit more painful and last a while longer.
