From how they grow to how they go, three researchers find out crawling is much more than just a transitional phase.
The qualities of movement are the topic of this video. Why do babies crawl? When do they learn this movement? How do they learn where and when to move in self protection? Fascinating topics of research and even more so for new parents. French researchers studied many babies, realizing they learn the processes but often at different times. Also realizing babies are born with many of their more mature movements in place, they simply lack the strength to practice them!!! The pull of gravity does not allow them the motion they practiced in the womb. When allowed to move freely in water newborns crawl, swim, reach and more. The personality of the baby and his adventuresome spirit have a great effect on when these changes take place.
A second topic of this video is growth rates of newborns/infants. In 1981, Michelle Lampl, a professor at the Center for the Study of Human Health at Emory University, Atlanta, began a study measuring the growth rate of babies weekly. There were 30 babies in the study. Lampl went to the homes of each of the babies measuring them weekly. She found normal growth rates. In order to have more exact measurements she requested funds to measure the 30 subjects twice a week. She found there were several infants who would go many days with no growth then experience a growth spurt. In order to closer verify her findings she believed it necessary to measure the growth rate daily. Her research showed babies do not grow at the rate indicated on the growth charts. Babies would not grow in length at all for several days or even a week. Then they would grow several centimeters in a day! This was hard to believe. Yet, the consistent results and the number of subjects made it undeniable.
In providing the previously discovered research findings to the medical community Lampl was met with great resistance. Trying to change established medical thinking, even when the research is verifiably authentic, is an uphill battle.
