It may be normal for a 3-month-old baby not to be able to grasp toys with both hands at the same time, and to be able to grasp with one hand, pronounce sounds and recognize sounds normally.
Generally speaking, the right hand, which is controlled by the left brain, is more flexible and agile than the left hand. Babies follow the same growth pattern during normal development, so it is normal for babies to be able to touch and hold things with one hand at around 3 months of age. At this time, babies are less able to localize objects and it is relatively difficult for them to grasp toys with both hands at the same time.
In addition, babies at this age can babble and differentiate between pleasant sounds and noises, and can also recognize the direction of sound to find the location of the sound, which suggests that babies’ ability to receive information and discriminate is normal.
There may be other reasons why a 3-month-old baby cannot grasp toys with both hands at the same time. Regular pediatric evaluation is recommended for early detection of abnormalities.
