One bit of magic is called “serve and return”. Watch out for your baby making a movement, a smile or a sound. Respond to them in a similar way, and add to it. So your baby might say “da!”. If you smile and say “yes, it’s daddy!” your baby will feel connected with you. It helps them learn to communicate, too.
Or your baby might look at something, and you can say what it is and show it to them. Then pause and see how your baby responds. Keep the chat going as long as your baby is interested. Even if you’re busy with housework or other tasks, it can be fun to playfully involve your baby by “chatting” about what you're doing.
