Eldest children are leaders
Eldest children tend to be ambitious, driven leaders. “The firstborn gets a lot of focus and attention as there are no other children for distraction,” says child and family therapist Meri Wallace, LCSW, author of Birth Order Blues. “The child can get lots of teaching, and so can grow up to feel very self-confident and strong enough to be a leader.” This leadership role was noted by Alan Stewart, psychologist at University of Georgia, in his 2012 definitive analysis of birth order studies. Plus, parents often task firstborns with helping with younger siblings and chores, which develops their leadership role. “Mom will say, ‘I have to take a shower, go watch the baby for a while,’ so the firstborn knows how to be responsible and nurturing,” Wallace says. “The firstborn gets lots of education in being a leader.” This is how your birth order can affect your health?
Older children are smarter
Much research, including a recent study from The University of Edinburgh, shows that oldest children tend to have higher IQs than subsequent children. This could be because parents provide more mental stimulation to their firstborn. “The time that parents have available to read to their first child, to explain things, is greater,” Wallace says. “Parents tend to talk to the oldest more—whether they’re home or going for a walk outside. Parents might ask ‘Why do you think the sky is blue?’ or ‘Why do you think the leaves are turning color?'” Older children then develop more analytic and conceptual thinking skills. This could be why 21 of the first 23 NASA astronauts were firstborns. “They have larger vocabularies and learn to think like adults, which is why they are so responsible,” says Linda Campbell, PhD, psychologist at University of Georgia and a leading researcher in birth order. But the downside of this added parental attention is that firstborns feel more pressured to do well. “The oldest can become a perfectionist, and then worry that if they don’t get things perfect they’re not valuable or lovable,” Wallace says.
