BACKGROUND In many cultures, simple herbal infusions, thin gruels, or sweetened water (agüitas in Guatemalan parlance) are given to infants and toddlers. Formative research has shown that the use of agüitas in early child feeding is deeply embedded in Guatemalan culture. OBJECTIVE We examined the prevalence and timing of the introduction of agüitas during early life in a low-income population...

Using online measures of familiar word recognition in the looking-while-listening procedure, this prospective longitudinal study revealed robust links between processing efficiency and vocabulary growth from 18 to 30 months in children classified as typically developing (n = 46) and as "late talkers" (n = 36) at 18 months. Those late talkers who were more efficient in word recognition at 18 mon...

We report a case of aspiration of calcium carbonate powder by a toddler. Bronchoscopic removal of aspirated contents resulted in favourable outcome.

Expressive language outcomes measured by MLU and the Index of Productive Syntax (IPSyn) at ages 3;0 and 4;0 were investigated in 34 late talkers with normal receptive language identified between 2;0 to 2;7 and 16 typically developing comparison children matched on age, SES, and nonverbal ability. Late talkers made greater gains than comparison children between 3;0 and 4;0 in both MLU and IPSyn ...

Juvenile court judges are asked to determine what is in the best interest of the child in every case they hear. As Judge Cindy S. Lederman writes, making these decisions without an awareness of the science of child development can be detrimental to the mental and physical well-being of the child. Yet until about a decade ago, court decisions were routinely made without taking into consideration...

Imitation is a common way of acquiring novel behaviors in toddlers. However, little is known about toddlers' imitation of undesired actions. Here we investigated 18- and 24-month-olds' (N=110) imitation of undesired and allowed actions from televised peer and adult models. Permissiveness of the demonstrated actions was indicated by the experimenter's response to their execution (angry or neutra...

This article discusses caries management by risk assessment for children age 0-5. Risk assessment is the first step in a comprehensive protocol for infant oral care. The program includes opportunities to establish a "dental home" and provide guidance for improved health outcomes. Risk assessment forms, instructions for use, and guidance-related education points have been included. Collaboration...

Twenty-two pairs of typically developing toddlers (M=24.32 months) and their mothers were observed in a play-room solving puzzles during 30 min. The target of the observations was hand-taking gesture. Researchers have thought that this gesture is rare among typically developing children and is more frequent among autistic children. Ten in 22 children showed this gesture in only 30 min. They sho...

Pictures are referential in that they can represent objects in the real world. Here we explore the emergence of understanding of the referential potential of pictures during the second year of life. In Study 1, 15-, 18-, and 24-month-olds learned a word for a picture of a novel object (e.g., "blicket") in the context of a picture book interaction. Later they were presented with the picture of a...

Three studies examined 24-month-olds' sensitivity to the prior accuracy of the source of information and the way in which young children modify their word learning from inaccurate sources. In Experiments 1A, 2, and 3, toddlers interacted with an accurate or inaccurate speaker who trained and tested children's comprehension of a new word-object link. In Experiment 1, children performed less syst...
