The bottle can influence whether the child will be right or left handed
Studies show that only 1 in 10 people is left-handed, and historically this percentage is always the same. Even inside the womb, only 10% of babies suck on the big toe of their left hand. Still, some researchers believe that the use of baby feeding bottles may influence whether he will grow left-handed or right-handed.
Scientists at the University of Washington conducted an experiment with more than 60, 000 babies from 5 different countries, which tracked how many months they breastfed and whether they developed right or left handed. According to the applied questionnaires, breastfeeding for more than 6 months may decrease the possibility of the child being left-handed by 3%.
In practical terms: the longer the breastfeeding time, the longer the brain lateralization develops, which makes the child equally prepared to be both right and left handed. With the use of bottles, a brain "decision" is anticipated.
The longer the breastfeeding time, the better for the child
Scientists also believe that these questionnaires showed that breastfeeding directly to the breast is essential for the child's full development until at least the ninth month of life. Already the process of lateralization of the brain begins shortly before the third month of pregnancy.
This is just one of the benefits of breastfeeding for a longer period of time. Breastfeeding up to 9 months is also associated with more right-handed people, higher intelligence, greater head circumference, lower likelihood of speech problems, and more.
Still, scientists ponder that it is not “artificial” breastfeeding that determines whether a child is left-handed or right-handed, but that she can anticipate a response that is usually defined during the fetal phase.
