Kirin's babbling -4m15d-

One day after the birth of my son, on the 137th day (4 months and 15 days), he hummed something like a short melody while recording a video. From there, I recorded my son's babble, connected the melody and attached the accompaniment.
The baby who did not know the vocalization method uttered various kinds of unheard words and voices every day like a vocal researcher (inventor).
Give him his first Christmas present.
