Explain the Sequence and Rate of Each Aspect of Development from Birth – 19 Years.

A, Physical:
Physical development starts from birth and within three weeks a baby will be able to use a grasp reflex, usually is able to hold hands tightly closed, in supine and prone position, will lie with head to one side. In the prone position will tuck knees up under the abdomen. Once a baby reaches 1 month old they will start to gaze attentively at faces, particularly when fed and talked to, Reflexes persist, startle reflex is seen less frequently when sitting at this early age the head will fall forwards (also known as head lag), and the back will be curved. At 3 months when sitting little head lag remains and the back is straighter. It is now that arms can be waved and bought together, legs can be kicked, and they will be able to turn from side to side. Babies now become more alert to their surroundings and will move their head to watch others; they will start to engage in hand and finger play and may start to be able to hold small toys briefly before dropping them. Rapid development continues and at 6 months babies are physically stronger and very alert. They will use their hands to play with their feet, and may take them to their mouth. They will be able to use the palmar grasp to pick up objects and pass them from hand to hand. At 9 months mobility makes a huge difference, babies can sit unsupported on the floor, they will go on their hands and knees and may even be starting to crawl or use an alternative way to move around, they may be able to cruise around a room on their feet using furniture to help them. This can be when pointing starts and poking at objects of interest with their index finger. At 12 months babies are becoming increasingly mobile and may even be starting to walk, they will be sitting down from a standing position, they will clasp hands together and use sophisticated pincer grasp and release hold of an object intentionally. Feeding themselves with a spoon and eating finger foods starts to become interesting around this time. At 15...
