Guide visual development
Three-month-old babies can already see objects 4-7 meters away. We can use toys to Doby them, but we should avoid making them squint at objects for a long time, so as not to squint.
Training listening comprehension
Babies aged 3-4 months are very sensitive to sound. We can train them to identify the source of sound and let them listen to different kinds of music and feel the melody and rhythm.
Enhance motor function
The 3-month-old baby has begun to have some basic sports abilities, such as raising his head and turning his head. We can use these abilities to enhance the baby's motor function through proper training.
Exercise hand muscles and coordination.
The baby's hand movements also begin to develop at this stage. We should always provide some toys suitable for babies to grasp, so that they can exercise their hand muscles and coordination ability.
