What It Proves: His hearing is developing, and he is victimization his brain to make out sounds.
Babies ar ready to hear from birth, however it takes a number of weeks for them to be ready to filtrate the racket of daily existence outside the female internal reproductive organ. the concept that some sounds ar additional attention-grabbing than others (the boring roar of the air conditioning isn't as vital as an enormous sister's unforeseen shrieks of laughter) develops over time. The sound of music, especially, can eventually get a baby's attention, whether or not it's returning from a toy or your stereo. Once you see your baby react to sound by searching for the supply, you may understand his ears ar healthy and he is growing inquisitive about what he is hearing.
