18 to 24 Months

Language development has great variability between 0 and 2 years old. The following parameters are only shown as examples. See also Developmental and Language Difficulties – Warning Signs.

   From the age of 18 to 24 months old, the child:  

  • has a vocabulary of 250 to 300 words (with more and more verbs), including some parts of the body and the possessive adjectives “mon/ton” (at around 20 months old)
  • understands instructions with one or two elements (“donne le toutou”) 
  • makes small sentences of two or three words (“pati maman,” “encore lait,” “veux pomme”)
  • likes to repeat or imitate words
  • says his/her name, says “moi/toi” 
  • answers “non!”
  • pronounces words better and better, but is not always able to say word endings or groups of two consonants (like “br” or “cr”)
  • can pronounce from 50% to 75 % of the sounds of French (at around 24 months old)
  • doesn’t use many articles (for example, “un,” “une” or “les”)
  • begins to understand the use of gender and number in French grammar

Written in simple language, it contains useful information classified by the age of the child, and practical advice in French and English for life in a bilingual family (e.g. what the parents who speak different languages can do to support their child's language development). Interestingly, the author suggests the use of a few American sign language (ASL) gestures for the period from birth to six months, to allow the child to express a few basic concepts (I love you, thirst, hunger, etc.) that both parents can understand.
  • Comment la parole vient aux enfants (Bénédicte de Boysson-Bardies) Éditions Odile Jacob, 2010, 289 p. | A very detailed reference book on language development from birth to 24 months of age. From the "preparation" of an infant even before his/her birth to the explosion of vocabulary at 24 months, this psycholinguist explores a child’s language development progression, step by step.
  • Votre enfant apprend à parler (Jean-Adolphe Rondal), Éditions Mardaga, 1998, 110 p. | A classic book about the stages of language development in children, written for parents and educators. Written by a renowned specialist, the book reminds us that language learning is rooted in the relationship between the child and the child’s parents. The child’s first words, usually spoken at around the age of 12 months, are preceded by thousands of moments of non-verbal communication (gestures, smiles) and verbal communication (little noises, listening, vocalizations) between the child and the child’s family circle. Each chapter is devoted to a particular aspect of the child’s progress from the first year to the age of six, and addresses the issues of developmental delays and possible language difficulties and what parents can do about them. Each chapter concludes with a list of benchmarks summarizing the concepts introduced, as well as detailed advice for parents to support their children.
