Evidence-based ways to build oral language skills through shared reading, questions, vocabulary, and bilingual family routines for preschoolers.

A toddler who puts a toy “in the box” when asked may seem to have mastered the word in. But change the objects, remove the pointing gesture, or ask the child to explain where something is, and the same concept may suddenly become harder. That distinction matters in spatial concepts language development. Children do not…

A child can sound perfectly understandable at home and leave a grandparent, teacher, or unfamiliar adult asking, “What did they say?” That difference does not automatically mean something is wrong. Speech intelligibility by age develops gradually, and how clearly a child is understood depends on far more than whether individual sounds are pronounced correctly. Listener…

Speech development delays rose modestly in some post-pandemic data. Learn practical, evidence-based ways parents can monitor and support language.

Language Acquisition Research can help parents and educators connect speech milestones with evidence, context, and careful observation.

Childhood speech delays have risen in several datasets. Learn what the evidence shows, what remains uncertain, and how families can respond.

ASHA Communication Milestones help parents review speech, language, and hearing skills from birth to age 5 without replacing evaluation.

A child may understand “Put your shoes on before we leave” yet struggle with “Touch the red block before the blue one.” That difference is central to understanding when children understand before and after: learning these words is not simply memorizing two definitions but learning how language can rearrange the order of events. Familiar routines…

A child can describe what is happening long before they can easily explain what might happen. Understanding when children use if then means looking at that shift: from talking about visible events to linking a possible condition with a consequence that has not happened yet. “If you put the block there, then the tower might…

A child who says “I wanted the red one, but…” may sound as if they have mastered a sophisticated piece of grammar. Yet knowing when children use conjunctions requires looking beyond whether the word appears at all. “And,” “but,” and “because” do different jobs, and children can begin producing them before they fully understand every…

Teacher discourse strategies can shape bilingual preschool talk. See what recent studies support, what remains uncertain, and what to try.

A two-year-old may seem to move quickly from scattered words to combinations that suddenly sound more organized. New research suggests that language development around age two may involve something deeper than simply collecting more vocabulary: the relationships between words themselves appear to become more complex. That does not mean every child experiences a dramatic language…
