This timeline is correct and includes all the main stages every child will go through and the milestones they will meet, although they may meet these stages at different rates then others because every child is an individual and develops at their own rates.
Development for ages 0-3 years.
Physical Development :
There is a recognised pattern of physical development that children are expected to follow. From birth a child is born with reflexes which are involuntary movements from a specific stimulus such as : the rooting reflex – the newborn will move its head towards anything that strokes its cheek or mouth, sucking reflex – this causes the newborn to suck anything that touches the root of their mouth, walking reflex – when the soles of their feet touch a flat surface they will attempt to walk by placing one foot infront of the other and the moro reflex – the trigger of this reflex can be a loud noise which startles the baby and their arms and legs stretch outwards. All these reflexes will eventually disappear once the baby has further control over their actions.
