At about nine months of age, most babies begin to notice the sounds animals make. They also delight at rhyming and silly sounds. Old MacDonald is a fun song that incorporates both animal noises and silly sounds.
Old MacDonald had a farm,
Eee-i-eee-i-o,
And on his farm he had a dog,
Eee-i-eee-i-o.
With a woof-woof here
And a woof-woof there,
Here a woof, there a woof,
Everywhere a woof-woof.
Old MacDonald had a farm,
Eee-i-eee-i-o.
Continue the song, substituting other animals and the sounds they make. You can make this activity even more fun by accompanying each animal verse with a corresponding stuffed animal or puppet singing the song with you and your baby.
