It revealed twins have twice the rate of late language emergence than singleton children; 38 per cent for twins compared to 19 per cent for singletons. In this study, 71 per cent of two-year-old twins were not combining words, compared to only 17 per cent of single-born children.

Do twins have more developmental delays?
Conclusions: Healthy twins should be considered at a higher risk for developmental delay. Whether these results are comparable to preterm singletons, or whether there are twin-specific issues involved, should be further investigated in a study that uses a matched singleton control group.
Do twins progress slower?
Multiples do tend to be born smaller than single babies. But it’s not because their growth rate is necessarily slower — in fact, for twins, it’s about the same as any other baby’s until about weeks 30 to 32, when they do slow down a tad, since they’re competing more for nutrients.
Do twins develop language slower?
For more than 80 years, we’ve known that – on average – twins develop language more slowly than single children (e.g. Day, 1932). More recent studies have shown that: twins – particularly boys – have a higher risk of developmental language disorders than single children (e.g. Hay et al., 1987, Rutter et al., 2003); and.
Do twins learn faster?
Look at Normal Milestone Ranges
The average range for learning to walk is 9 to 18 months. That is a 9-month difference! That makes one twin learning to walk at 10 months and the other at a year seems like a small variance.
Are twins less intelligent?
Twins on the average seem to have lower IQs than singletons. The best estimate for this group difference is 4.2 IQ points (less than one-third of a standard deviation), with a great divide between study outcomes of less vs more recent birth cohorts (5.1 vs 0.5 IQ points, respectively).
Do twins have learning disabilities?
The relationships between genetic, perinatal and social factors and learning disability were also determined. It was found that 12.5% of twins had learning disabilities. The most common neurodevelopmental dysfunction were language disorders, poor graphomotor fluency and poor fine motor dexterity.
What age should twins start talking?
When Your Twins Should Start Talking. By 18 months, your twins should be able to say around twenty words. These will be simple words like mama and dadda. Your children will use various sounds and rhythms to “talk” as they play and interact with others.
How does being a twin affect development?
Most previous studies reported that twins have lower cognitive ability than singletons. In a very large study of children born in Birmingham, United Kingdom, between 1950 and 1954, twins had a deficit in verbal reasoning scores at age 11 of 4.4 points on average.
Are twins usually speech delay?
LAWRENCE — A study of 473 sets of twins followed since birth found that compared with single-born children, 47 percent of 24-month-old identical twins had language delay compared with 31 percent of nonidentical twins. Overall, twins had twice the rate of late language emergence of single-born children.
Can twins be autistic?
The severity of autism traits and symptoms in the twins was measured by a clinician’s assessment or by parents’ ratings on a standardized questionnaire. Some cases were diagnosed by both methods. The researchers determined a 96% chance that if one twin has ASD, the other has it, too.

Why do twins have lisps?
Although twins are more likely to experience certain perinatal factors that can contribute to speech delays like premature birth and lower birth weights (Bowen, 1999), twin speech delays can most often be traced back to social-language experiences.
Why is raising twins so hard?
The hardest thing about having twins is…
“Managing the movement of two babies. Carrying them both up and down the stairs, getting them into the car, etc.” —Simeon R. “Often having to make one baby wait!” —Catharine D. “Being outnumbered—the logistics of two on one is definitely the hardest.
What age do twins start playing together?
Between 6-12 months
Between 6-12 months your babies will begin to start playing alongside each other.
Do twins understand each other?
Young twins are together nearly all the time, and like any two people who spend most of their time together, they learn to rely on nonverbal or shorthand forms of communication. They’re able to act intuitively, understanding each other’s gestures, grunts, or vocalizations.
Are twins less successful?
The researchers used data on 13,800 twin births between 1967 and 1978 to show that females exposed in utero to a male twin are less likely to graduate from high school (-15.2 percent), to complete college (-3.9 percent) or to get married (-11.7 percent).
Do twins have similar IQ?
Researchers found that the twins had “substantial differences” in their IQ. Tests revealed that the adopted twin had an IQ 16 points lower than her long-lost sister. This contradicts existing research that says identical twins usually have no more than 7 points difference in their IQ.
Are twins more successful than singletons?
Conclusions These data support the proposition that twins perform less well academically than singletons. Low birth weight has a negative association with subsequent academic achievement in early adulthood, with the effect being stronger for twins than for singletons.
Do twins have a higher rate of autism?
Using a mathematical analysis of data, his team found that identical twins were much more likely to have similar levels of autistic symptoms than fraternal twins. Those researchers also concluded that: High levels of autism symptoms are genetic in origin. Less severe symptoms are not as likely to be inherited.
How does being a twin affect your personality?
Twin psychology has been studied to a very limited extent. Only few remarkable peculiarities of the twins’ development are known for sure, such as delayed intellectual development, language retardation with frequent cryptophasia, difficulties and fragility of self consciousness, reduced sociability.
