Till the fourth month or so, your baby will not be able to properly lift and grasp objects. He/she would have been so far just used his grasping skill as a reflex and his hands would be clenched in a fist.
But between the fourth and eighth months, your baby’s hand-and-eye coordination will undergo a major overhaul. He/she will be able to pick up large objects. This is a good time for parents to provide their children with building-block games. At the same time, remember to keep hazardous substances away from your baby.
Your baby’s attention span time would be very brief and he/she may get over certain toys in a very short time. As a result, you may see him/her throwing objects from his/her hands too. This does not mean that his/her grip or strength is subpar. Also at time he would mindlessly bang the objects, just to see the kind of noise it makes on different surfaces. He would also have an innate curiosity to just see what is inside his/her toys and may wish to bang and break them.
One more thing to be careful of during this time is your baby’s tendency to put everything in his/her mouth. Hence, one should never leave the baby unguarded.
One important development that sets in generally sometime between the ninth and twelfth month is your baby’s preference for either his/her left or right hand.
Alongside your baby’s pincer grasp will develop during this time. By using the tip of the thumb and forefinger, he will be able to pick up small objects between his/her thumb and forefinger.
And then there is no stopping his/her. He/she will pick up things and hurl them – all in the spirit of play. By the time he/she is about to celebrate his/her first birthday, he/she would have become quite a pro at playing pick and throw.
