Aiyoh, speech delay is worrying kan, a few of us tried talking more to our kids, reading books together every day, and making eye contact when we speak so they see our mouth movements, it really helped! But honestly, I think best you check with your paediatrician or a speech therapist to know what's going on and get proper guidance, because every child is different and they can assess if ada any underlying issues ke. My friend's son juga had delay, therapist gave her exercises to do at home which made a big difference, so don't worry, early action helps a lot.
