In what situation should parents bring their child to a speech therapist?

Options aren't very useful. There are milestones for speech that need to be observed. My kid wasn't talking or babbling much by 1.5 yrs old, not even mama or dada with intentionality. Got a referral to KKH Department of Child Development to get his professionally assessed and into speech therapy classes. I find that early intervention is so important and helped us to understand and learn how to help him.

If my child is not talking for longer periods and is being quite in social gatherings

If my child is not speaking well and finding it difficult to communicate

I believe there are developmental milestones for speech to refer to.

If my child is not speaking much or interacting with her friends

Probably depends if it hurting his interactivity with others

When they are anti-social and have very limited vocabulary

Also when the child cannot construct a proper sentence.

If the kid is not speaking or mumbling or stuttering

I wouldn’t bring them if it’s not necessary
