The composition of young children's vocabularies in 7 contrasting linguistic communities was investigated. Mothers of 269 twenty-month-olds in Argentina, Belgium, France, Israel, Italy, the Republic of Korea, and the United States completed comparable vocabulary checklists for their children. In each language and vocabulary size grouping (except for children just learning to talk), children's vocabularies contained relatively greater proportions of nouns than other word classes. Each word class was consistently positively correlated with every other class in each language and for children with smaller and larger vocabularies. Noun prevalence in the vocabularies of young children and the merits of several theories that may account for this pattern are discussed.

Our study has demonstrated for the first time that the infant calming response to maternal carrying is a coordinated set of central, motor, and cardiac regulations and is a conserved component of mammalian mother-infant interactions. Our findings provide evidence for and have the potential to impact current parenting theory and practice, since unsoothable crying is the major risk factor for child abuse.

This study investigated and compared ideas about parenting in Argentine, Belgian, French, Israeli, Italian, Japanese, and U.S. mothers of 20-month-olds. Mothers evaluated their competence, satisfaction, investment, and role balance in parenting and rated attributions of successes and failures in 7 parenting tasks to their own ability, effort, or mood, to difficulty of the task, or to child behavior. Few cross-cultural similarities emerged; rather, systematic culture effects for both self-evaluations and attributions were common, such as varying degrees of competence and satisfaction in parenting, and these effects are interpreted in terms of specific cultural proclivities and emphases. Child gender was not an influential factor. Parents' self-evaluations and attributions help to explain how and why parents parent and provide further insight into the broader cultural contexts of children's development.

Evidence of psychological distress in families during COVID‐19 outbreak are arising. However, the perceived changes in psychological adjustment during home confinement with respect to the period before the pandemic have not been addressed yet. Moreover, little is known about the role of coparenting and specific COVID‐19 contextual variables on parental stress and children's behavioral difficulties in the Italian context. Using a cross‐sectional survey, we collected data on 841 Italian parents of children aged 3–11 years with typical development during the home confinement (20th April–18th May). We analyzed levels of parental stress, coparenting, and child externalizing behaviors before and during the home confinement. Additionally, hierarchical regressions were performed to investigate predictors of parental stress and child externalizing behaviors during the lockdown. Results showed that parental stress (especially in mothers) and child externalizing behaviors increased during the lockdown period. Coparenting was a strong predictor of parental stress, together with being a mother, younger child age, less time dedicated to the child, and scarce feasibility of remote working. Besides, child externalizing behaviors were predicted by male gender, less parental time dedicated to the child, higher parental stress, and child distance learning workload. Our findings indicate a negative impact of COVID‐19 lockdown in both parents and children, suggesting that positive coparenting and time dedicated to children may help to reduce the detrimental effect of pandemic restrictions on family adjustment.
