We express meaning with words, but also with our intonation and body language. Your child is learning this from your examples at this level, while practicing the sounds they can make and the reasons they interact with you.
Your child is learning they can have an effect on other people. When they wiggle or make sounds, they can get you to look at them, or come to them or talk to them. They are learning to initiate interactions, which is really important at all levels of communication.
In older children, initiation can fade away (extinguish) because people no longer respond to their attempts. Make sure you are showing your child that you value their initiations.
Today’s activity: Give attention when your child wiggles or makes a sound. Look and smile and, if there’s time, do a short back-and-forth social exchange.
