In the initial months after birth, babies would mostly express their needs to parents by crying. As they advance in age, the sobbing gets replaced by amazing squeals of laughter which is a very effective way of letting their near and dear ones know of their appreciation of things going around them.
Laughing is an important mode of communication as a baby laughs approximately three hundred times every day, whereas an adult laughs only twenty times . The common sounds of laughter emitted by the baby at the beginning is a low chuckle, cooing or gurgling that ultimately transforms to a full on belly laugh [1, 2].
When do babies start laughing
Babies usually laugh out loud for the first time when they are about three to four months of age though some may acquire this skill in their fifth or sixth months. Their laughter may be a result of anything funny or amusing that has caught their sight .
The babies’ first laugh will not just leave their parents spellbound but also shock or surprise the little ones because of the suddenly emitted noise. Gradually the kid will enjoy listening to his voice as well as watching others enjoying his laughter and by the fifth month the low squeals or giggles will transform into a complete belly laugh. Moreover, by producing a lot of squealing, cooing and other sounds, they are learning the proper usage of their mouth and tongue, which in turn will be beneficial for speaking .
Till six months, infants laugh in response to any auditory or tactile stimulus like tickling, hearing funny noises and blowing raspberries. As their brain and sense of perception matures further after the sixth month, they begin to grow humorous, laughing at their own tricks like throwing things out of the basket or while playing a pass-and-snatch game with their parents [1, 2].
