It's known that human beings learn through play. A delay in play skills means a delay in other skills.
Toys are not necessary for play, of course. All that’s needed are two people interacting in a fun way. But children’s toys can be useful for engaging the attention of a baby and even more useful for expanding circles of communication and teaching other developmental skills along the way.
You can give your baby their first music toys soon after his/her arrival - listening to the gentle soft sounds is beneficial for the little one's hearing development. A bit later he/she will try to find the source of the music.
Make cute photos of your baby with the first music toy, upload to the App. Write about his/her reaction to the sounds.
