„Learning at home is also heavily influenced by parents’ use of words and gestures around their children. Movement of the hands or head when having a conversation makes a difference – researchers have found that this strongly correlates with later language ability in their children and that disadvantaged parents are less likely to use gestures, perhaps due to lack of confidence or stress. At the age of 14 months, children from higher socio-economic status (SES) families are gesturing more than their lower SES peers, and this gesture use is related to later vocabulary skill.“
