In order to train your baby’s ability to find sound and head control, you can use a small box or a small sand hammer/rattle to gently shake the sound-making object for 3-15 seconds at a distance of 10 cm from your baby’s left and right ears respectively when your baby is lying on his or her back in the midline position to attract your baby’s attention and let him or her find the sound-making object quickly. When the baby is in the prone position, use a vocal toy to tease the baby to raise his head. These exercises can also cultivate baby’s interest, strengthen the cognitive ability of objects and promote the development of baby’s prone head raising ability. It is important to practice in a relatively quiet environment and to elicit a listening orientation response without looking at objects.
