Alhamdulillah, pagi ni wawa dapat ilmu baru dari Puan Nadiah berkenaan dengan perkembangan bayi dan kanak-kanak yang normal.
These developmental norms may provide clues:
Before 12 Months
It's important for kids this age to be watched for signs that they're using their voices to relate to their environment. Cooing and babbling are early stages of speech development. As babies get older (often around 9 months), they begin to string sounds together, incorporate the different tones of speech, and say words like "mama" and "dada" (without really understanding what those words mean).
Before 12 months of age, babies also should be attentive to sound and begin to recognize names of common objects (bottle, binky, etc.). Babies who watch intently but don't react to sound may be showing signs of hearing loss.
By 12 to 15 Months
Kids this age should have a wide range of speech sounds in their babbling (like p, b, m, d, or n), begin to imitate and approximate sounds and words modeled by family members, and typically say one or more words (not including "mama" and "dada") spontaneously. Nouns usually come first, like "baby" and "ball." Your child also should be able to understand and follow simple one-step directions ("Please give me the toy," etc.).
From 18 to 24 Months
Though there is a lot of variability, most toddlers are saying about 20 words by 18 months and 50 or more words by the time they turn 2. By age 2, kids are starting to combine two words to make simple sentences, such as "baby crying" or "Daddy big." A 2-year-old should be able to identify common objects (in person and in pictures), points to eyes, ears, or nose when asked, and follow two-step commands ("Please pick up the toy and give it to me," for example).
From 2 to 3 Years
Parents often see huge gains in their child's speech. Your toddler's vocabulary should increase (to too many words to count) and he or she should routinely combine three or more words into sentences.
Comprehension also should increase — by 3 years of age, a child should begin to understand what it means to "put it on the table" or "put it under the bed." Your child also should begin to identify colors and comprehend descriptive concepts (big versus little, for example).
