This month we are featuring fun experiments you can do with your baby from the book Experimenting with Babies<\/i><\/a>. <\/i>Babies are sweet and cuddly and full of scientific experiments. What will your baby teach you?<\/p>\n Age range: 0\u20136 months Introduce a jingly toy to your baby by showing it to her and shaking it. Put the toy in her hand and allow her to grasp it. Then touch her feet with the toy. Next, place the toy near your baby so that she can grasp it if she reaches out to it. Then place the toy near your baby so that she can touch the toy with her feet if she moves them.<\/p>\n Your baby will be able to touch the toy with her feet about a month earlier than she can reach out and grasp it with her hands.<\/p>\n It\u2019s long been thought that babies gain control over their bodies in a top-down progression. First, they learn how to control their head movements; then their arm movements; then, toward their first\u00a0birthday, they learn to control their legs and feet in order to sit, crawl, and walk. But experiments like this one suggest that babies can control their legs earlier in the process than previously understood.\u00a0In a 2004 study, researchers placed infants in a seat that allowed their arms and legs to move freely. During some sessions, they placed the jingly toy at the infants\u2019 shoulder height and within\u00a0arm\u2019s length, toward the middle of their bodies, so that merely raising their arms would not make contact with the toy. During other sessions, they placed the toy at the infants\u2019 hip height and within\u00a0leg\u2019s reach, also toward the middle of their bodies. On average, the infants were able to touch a toy with their feet at 11. 7 weeks, about a month before they were able to reach for and grasp a toy with\u00a0their hands (at 15. 7 weeks). It is interesting that by the time the infants were able to touch the toys with their hands, they still spent an equivalent amount of time touching the toys with their feet,\u00a0even though the hands have the ability to grasp the toy and the feet do not.<\/p>\n The researchers postulate that babies are able to reach for a toy with their feet before they can reach with their hands because of differences in the anatomical structure of the hip and shoulder\u00a0joints. The hips have a limited range of movement compared with the shoulder, which might mean the degree of control required for intentional leg movements is less than for intentional arm movements. Because the arms have a greater degree of movement than the legs, this might also mean that not only are arm movements more difficult to control but also it is less likely that a specific pattern of motion will already be familiar to the child. As with adults, practicing a particular pattern of motion \u2014 for instance, a dance step \u2014 makes it easier to perform, and so the practice that babies get making a low number of distinct leg movements (relative to arm movements) may give their legs an edge.<\/p>\n Some people might be surprised by the results of this experiment, but any mom who has experienced the third trimester knows not to underestimate those tiny feet, which probably spent a good deal of\u00a0time practicing kickboxing in her uterus. It\u2019s natural to assume, though, that a baby would use her hands to reach for an object because that\u2019s what older kids and grown-ups would do. But remember:\u00a0Your baby\u2019s developing body has a set of processes that have their own logic, which are not always what we might expect. Fortunately, as in many other cases, she\u2019ll try to improvise.<\/p>\n Excerpt originally appeared in Experimenting with Babies.<\/a>\u00a0<\/i>Shaun Gallagher shows parents how to recreate landmark scientific studies on cognitive, motor, social and behavioral development \u2014 using their own bundles of joy as the research subjects.<\/p>\n Shaun Gallagher\u00a0is an author of two nonfiction books, “Experimenting with Babies<\/a>” and “Correlated.” He is a former magazine and newspaper editor\u00a0and runs the website Correlated.org<\/a>, on which “Correlated” is based.<\/em><\/p>\n Experimenting With Babies: 50 Science Projects You Can Perform on Your<\/a><\/em> Kid<\/em>\u00a0<\/a>shows parents how to recreate landmark scientific studies on cognitive, motor, social and behavioral development \u2014 using their own bundles of joy as the research subjects.<\/p>","protected":false},"excerpt":{"rendered":" This month we are featuring fun experiments you can do with your baby from the book Experimenting with Babies.
