However, most pass through an identifiable skill “set” along the way. Called developmental milestones, these are skills that build on each other, from simple to complex, during predictable time periods. For example, a child must babble single syllables (4-6 months) before multiple syllables (7-9 months) before speaking 2-word sentences (18-24 months) . Milestone charts represent a “timetable” for mastery of these skills—a guide to “normal” development. Keep in mind, however, that children vary in  \ntheir development and that an individual child may develop more quickly in one area than in another.  \nBelow are general guidelines for hearing/auditory, cognitive, speech (sound production) and language (listening, understanding and using words) development. Most children will demonstrate these skills within six months of the times listed. In reality, these areas overlap, as development in one area is reinforced and enhanced by growth in others.  \nBirth-3 Months  \nHearing  \nAuditory detection/attention:  \n• Reacts to loud sounds with startle (Moro reflex)  \n• Reacts initially to sounds that are close by; between 2-4 months begins to develop distance hearing  \n• Responds to LF sounds (vowels) better than to HF sounds (consonants)  \n• By the end of the third month, an infant recognizes his mother’s voice; stops crying to listen; listens to his/her own sounds  \n• Enjoys only a few noisemakers  \nSpeech  \n• Infants are unable to control motor movements; therefore, most actions are reflexes. The most important reflex for speech development is the rhythmic suckswallow pattern, established three months prior to birth.  \n• Produces sounds such as fussing, crying, burping and cooing.  \n• Produces most sounds on exhalation with lengthy vowel-like sounds (back vowels)  \n• Makes single vowel sounds “ah”“eh” “uh” -one syllable  \n• Sustains cooing 15-20 seconds  \n• Different kinds of crying for pain and hunger  \nLanguage  \n• Attends to speaker’s mouth or eyes  \n• Moves in response to voice  \n• Expresses feelings by cooing (one syllable- “ah”), gurgling (at back of throat) and crying (E)  \n• Exhibits differentiated crying (E)  \n• Vocalizes to caregiver’s smile and voice and to express pleasure (E)  \nCognition  \n• Responds to and imitates facial expressions of others (Meltzoff & Moore, 1977)  \n• Recognizes bottle or breast  \n• Briefly looks at objects  \n4-6 Months  \nHearing  \n• Turns eyes/head to search for sounds  \n• Enjoys hearing own sounds (gurgling, laughing and babbling), auditory feedback loop develops  \n• Enjoys sound of musical toys (rattles, bells)  \n• Responds to voices by babbling  \n• Begins differentiating between environmental and speech sounds  \n• After hearing the mother’s voice, cries if the face he/she then sees isnot the mother’s face  \n• Recognizes familiar sounds for feeding (e.g. a spoon in a dish)  \nSpeech Language Cognition  \n• Vocalizes in self-initiated sound play  \n• Coos to music  \n• Vocalizes “ma” or “mu”  \n• Tries to repeat heard sound sequences  \n• Babbling begins  \n• Experiments and plays with sounds (yells, gurgles, blows raspberries and bubbles)  \n• Varies volume, pitch and rate (suprasegmentals)  \n• Smiles at speaker (R)  \n• Vocalizes to objects (E)  \n• Laughs  \n• Says “mama/dada” without meaning (E)  \n• Babbles to gain attention (E)  \n• Shows pleasure/displeasure by vocalizing (E)  \n• Explores with hands and mouth  \n• Smiles/vocalizes to mirror image; reaches out to mirror image  \n• Experiments with cause-effect: shakes rattle  \n• Reaches for objects  \n[Find more at](Find more at hearingfirst.org)[ hearingfirst.org](Find more at hearingfirst.org)  \n©2016 Hearing First, LLC  \nDevelopment Milestones-Birth to 8 yrs  \n7-9 Months  \nHearing  \n• In sitting position, turns eye/head/ body to source of sound (sound localization); has difficulty locating sounds above or behind  \n• Responds to simple requests  \n• Modifies speech to ma","cbCaibF1TBCijEaM","https://ap.wps.com/l/cbCaibF1TBCijEaM","pdf",364072,6,"English","# Developmental milestones\n## General principles\n## Birth–3 months\n## 4–6 months\n## 7–9 months\n## 10–12 months","[{\"question\":\"What are developmental milestones and how should they be used?\",\"answer\":\"Developmental milestones are skills that build on each other from simple to complex during predictable time periods.
