hi, my LO is 25 mths old. He refused to talk and can only says mama, school, apple. And only point to things and says hmm or ahh at times. He attend PG and the teacher says it normal and mentioned that Some kids don't talk til 4yrsold. He understands wat others says and can recognize lots of words by pointing at them when asked too. He enjoys flashcards too. I try reading lots of books to him and he enjoys the storytelling session. Any advice on how to encourage him to talk and when should I formally seek professional help like speech therapist? Thanks
