About 12 Months: A Sense of Humor
As your baby starts to develop language skills, her sense of humor also emerges. "Babies this age laugh and laugh if you make silly noises," says Dr. Cowan. When your baby thinks something is funny, she wants to get a reaction out of you, too, so laugh along with her. Drop something on the floor, or make a funny face -- she'll find it hysterical. "Surprise is a big element in making babies laugh at 12 months," says Dr. Garcy. "Put your baby on your knees, sing a song, and then gently let her drop a bit." Take advantage of this fun stage; it's not every day you find someone who thinks you're the most hilarious person on earth!
