It is formed by the lower part of the femur, the tibial plateau and the knee cap. It enables hinge and rotating movements as the connection between the upper and lower leg. This means that we can not only bend the lower leg backward but also rotate the lower leg and foot towards the upper leg.
By the time they're 9 months old, most babies have developed the fine motor skills â the small, precise movements â needed to pick up small pieces of food and feed themselves. You may notice that yours can take hold of food (and other small objects) between forefinger and thumb in a pincer grasp.
During a babyâs first year they will triple their birth weight[1] and increase in length by 50%. To fuel their amazing physical and mental development, eating is a top priority! With tummies too tiny to eat a lot, babies compensate by eating nutritionally rich foods often. Learn about your babyâs nutritional needs during each of the following life stages: Newborn â 4 Months. Remember that your baby relies on breast milk or formula as the primary source of nutrition until at least 12 months of age. Age range: Newborn to 4-6 months: At this age, the best and only food for your little one is mother's milk, infant formula, or a combination of the two. Allow your baby to determine just how much and how often he or she needs to eat. Some babies eat every two hours, day and night; others will go for longer without eating. While in general itâs best to feed your baby 'on demand,' for the first few weeks the American Academy of Pediatrics recommends waking your baby every 3-4 hours if he or she is not doing so on their own.
