• Del nacimiento al primer mes, los bebés lloran para pedir ayuda.
• Alrededor del segundo mes, los bebés pueden distiguir entre el balbuceo y el habla.
• Al tercer mes, los bebés producirán sonidos alargados de vocales, como, por ejemplo, aaaa u oooo.
• En el cuarto mes, probablemente, los bebés imitarán el habla normal.
• Cuando el bebé tiene 5 meses, todavía experimentará con balbuceo.
• A mitad del primer año del bebé (6 meses), el infante variará el volumen de su balbuceo.
• A los siete meses, los bebés producirán su balbuceo con un solo respiro.
• Al octavo mes, los bebés podrán repetir vocales enfatizadas.
• Al 9no hasta 10mo mes, los bebés podrán imitar los sonidos del habla humana, como del balbuceo de otros infantes.
• Undécimo mes cumplido, los bebés podrán imitar rimas.
• Finalmente, al primer año cumplido (12 meses), los bebés tendrán una o más palabras incluidas dentro de su vocabulario.
