The muscles are stronger and the movements become more defined. Jumpy hand movements are softer and smoother, clenched fists are now released and the fingers are more relaxed and open.
By the end of the third month, the grasp reflex weakens considerably, but is not entirely gone; babies are still unable to grasp an object voluntarily. By the end of the third month, babies begin to strike at objects purposely, which is the first expression of eye-hand coordination.
By 8-10 weeks, babies' eye muscles are stronger, and they can focus on objects placed in their field of vision, and even track their movement; as eye-hand coordination progresses, babies can move their head to continue tracking a moving object.
Babies now reach a breakthrough discovery: they become aware of their own hands. Babies are fascinated by this discovery, and continue to explore their hands by gazing at them and putting them into their mouth. Random strokes at an object stir babies to turn their heads towards it. The discovery of the hands and the control they have over them opens a new world of experiences. Next, babies look at an object and try to reach it. Initially, these attempts may be strictly trial and error, but by the end of the third month, following frequent practice, babies reach out and strike at objects with purpose and intention.
