Begin to vary the pitch and tone of the sounds you are making with your baby. They may tune in to the different ranges and be encouraged to copy the sounds. The sounds that your baby will make may differ from yours, remember to praise them for joining in. Try to find two objects that are the same, but are different sizes, for example, a small book and a big book. Show them the small book, using a high voice say, “Small book.” Wait for your baby to try to respond. Next, show your baby the big book and in a low voice say, “Big book.” Again, give them plenty of time to respond.
