Laughter is good for baby's brain development. There are many other benefits of laughter in babies. Therefore, it often took the little laugh. However, it was not all babies are easy to laugh, there are a number of factors that influence it.
Although all babies look the same, the fact that every baby has a different temperament. Some babies are always active, move the hands, feet and mouth without stopping. There is also a calmer baby. So even there is a baby who responded warmly to the new people, while others tend to fussy babies.
Psychiatrist from the UK, Alexander Thomas and Stella Chess, classifying three basic types of child temperament: low, high, and medium. Mannered children are (easy child) generally have a positive mood, quickly establishing a regular routine in infancy, and easy to adjust to new experiences. Mannered children is high (difficult, child) tend to react negatively and frequent crying, difficulty starting the routine, and later received a new experience. While low-mannered son (slow-to-warm-up child) has a low activity level, somewhat negative, and shows low adaptability.
Well, the temperament of each baby is different is what determines whether the child also includes easy to laugh or not. Just so you know, the temperament to be a permanent characteristic of newborns who later updated by the experiences of children in the future. Infant temperament was influenced by heredity or nature of both parents. However, the effect depends on how large the response of parents and the experience of the environment experienced by the child. In short, parents and families have the most influence in establishing the character of children.
So, although still in its infancy, the child is able to respond to everything that made the mother or father. Similarly, when babies begin to laugh, how welcome parents, is always given a positive response to every laugh? If so, then the baby to learn, laugh is a good thing.
