At this age, your baby is likely beginning to babble and produce a variety of sounds. To build on this stage of language development, encourage your child to echo you as you make some of his most commonly produced sounds.
Step 1: Lean in close and make eye contact with your baby.
Step 2: Smile and repeat the sounds that you hear your baby say (Example: ma-ma-ma; ba-ba-ba).
Step 3: Listen to the next sound your baby makes.
Step 4: Smile and then change the sound just a little bit and see if your baby notices. Your baby might respond by repeating the new sound, laughing, becoming quiet or making the same noise she made at first.
