Toddlers' sleep difficulties have mainly been investigated from the mother's point of view, despite the fact that paternal implication seems to influence young children's sleep quality. This qualitative study aims to better understand how fathers experience toddlers' sleep difficulties by examining their sleep-related cognitions and strategies…

Recent research suggests that infants prefer prosocial behaviour. However, some studies have failed to report this preference, raising the question of which specific parameters allow it to be observed. We attempted to answer this question by investigating whether the preference varies (1) with age (by testing infants aged 6, 12 and 18 months), (2)…

Dynamic analyses of language growth tell us how vocabulary and grammar develop and how the two might be intertwined. Analyses of growth curves between 17 and 42 months, based on longitudinal data for 34 children, revealed interesting patterns of vocabulary and grammatical developments. They showed that these patterns were nonlinear, but with…

Previous research using the name-based categorization task has shown that 20-month-old infants can simultaneously learn 2 words that only differ by 1 consonantal feature but fail to do so when the words only differ by 1 vocalic feature. This asymmetry was taken as evidence for the proposal that consonants are more important than vowels at the…

A fundamental question in developmental science is how brains with and without language compute numbers. Measuring young children's verbal reactions in Spain and Finland, we show that, although there is a general arithmetic ability for small numbers that is shared by monkeys and preverbal infants, the development of such initial knowledge in…

This collection of six case studies is a by-product of a European-focused study that sought to understand the policies focused on children from birth to age 3, whether directly affecting the children or reaching them indirectly through their parents.
