Detailed explanation-1: -Gestures emerge around 9 months. By 12 months, common motions include waving, shaking the head, reaching, pointing, and clapping. Cultural gestures (thumbs-up or high-fives) emerge by 16 months. Symbolic gestures (shrugging shoulders to say “I don’t know”) emerge by 24 months.
Detailed explanation-2: -“Some linguistic specialists theorize [that] babies say ‘dada’ before they say ‘mama’ because they don’t identify mom as being separate from themselves initially, ” she explains. “Instead, their identities are fused.”
Detailed explanation-3: -Cross cultural research on baby’s first words shows that the clear winner is Dada. Tardif and colleagues found in over 900 babies, age 8 to 16 months from English, Cantonese, and Mandarin speaking homes, Dada was the most common first person identified.
Detailed explanation-4: -Between the ages of four and six months, infants start babbling as a way to test their articulatory skills. They’re more likely to utter the sound “da” because doing so doesn’t require him or her to force air through the nose.
