I was really worried with Kimi's speech development when he was 18 months old. He can only say 3 clear words then - Nanay, Tatay, and dede (milk). I even had him checked by his GP so we can get a referral to have a hearing test or to see a paediatrician if needed. She assured me that he is okay and didn't seem to have any hearing problem. But since I insisted, she sent a request for a hearing test appointment at the audiology department of the public hospital.
I made some research and found out that babies who are exposed to more than 1 language tend to speak a bit late. But it was still advised that best time to teach a kid another language is through exposure to the language since they are born. We continued with what we do to improve his language acquisition. We spoke to him slowly and emphasised the letter sounds and the words. We read to him his books especially the shape book which is his favourite at that time. We put him in family day care once a week since he was 20 months for social interaction. We still speak to him at home in 2 languages: Filipino (primarily) and English (as translation). His family day carer speaks to him in English together with the other kids in care.
And, at 21 months, his words increased dramatically that I got lost in counting the number of words he could speak both in Filipino and in English.
NB: This was long overdue.
