Grabbing

Newborn- the baby starts to grab objects. A baby is born with the grasping reflex. one example is when i would hold my pointer finger out my little newborn cousin would grap it with her hand.

Three Months- A baby can bat at toys and has sstarted to develop hand eye coordination. one example is my little cousin use to have this little toy with buttons and instead of pressing them she would bat or hit at them.

Four Months- a baby is now able to pick up large objects but still is not able to grap large objects because they haven't developed full finger dexterity. one example is when my cousins were little they would play with blocks of different shapes and they could hold on to them.

Nine to Twelve Months- now a baby has full finger dexterity and can pick objest up with litle or no effort. now you will be able to tell if a baby is left or right handed. now a baby can use the pincer grasp. one example is the little boy i babysit picks up his cherrios with his thumb and pointer finger with no problem but another bay i babysit has to pick up a cherrio with his whole hand and he has alot of effort. the diiference is one has pincer grasp and another doesn't have pincer grasp.

Eyesight

Birth- the brain isn't ready to process all visual information. The baby sees things very fuzzy. For example if you took your glasses or contacts off. The baby can focus no more than eight to fifteen inches away from him or her.

One to Two Months- the baby is consistently focusing both eyes and can see or track a moving object like a toy car! The baby is now starting to see colors.



Four Months- The baby is now starting to see farther and farther.

Five Months- The baby is now starting to see smaller objects like cherrios. The baby is still getting better at tracking moving objects and is now working on seeing different shades of colors.

Eight Months-The babies clarity and depth perception is almost that of an adults and they can now see all colors.

Head and Neck Control

I have made many observations of head and neck control. One example is when i was babysitting a 8 month old and he could lift his neck up by himself and he could scotch acrossed the floor by himself. Another example is when my cousin was just 1 month old when someone would hold her they would be very careful holding her head and when they passed her to someone they made sure the head was being held properly because she had very little head and neck control. Also when my cousin was a few months old and he was starting to walk he would wobble because his head was to heavy for him and his body(neck) control was not as strong as it needed to be. Those are three examples of head and neck control that i have observed.
