Baby illusion.
Many mothers reflect their youngest young gentleman is smaller than he or she actually is, according to new research. The determination may help explain why many of these children are referred to as the "baby of the family," well into adulthood. It also offers a sense why a first neonate suddenly seems much larger when a new sibling is born continued. Until the coming of the new child, parents experience what is called a "baby illusion," said the authors of the study, which was published Dec 16, 2013 in the weekly Current Biology.
