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.
Some 4-6 month old babies may not have started solids at all. At 6 or 7 months old, some infants may eat 4-6 ounces of food per day while babies who are just starting solids at 6 or 7 months of age may be eating only 1-2 ounces per day.
