Speech delay?

hi! as an ECH teacher we often see children (even at age 4>) who might not speak much, or have as extensive a vocabulary compared to others. it's totally normal because every child is different and will learn to do so at their own pace! at that age even blabbering or mumbling could be considered as initial stages of speech. i usually tell parents that they could read more storybooks, talk to their child more (children tend to pick up language from the adults around them!) or even sing more songs if they want to :) however, i understand your worry as well so if it's still a concern then speak to your pediatrician/doctor about it and do what you need to do.
