The lengths you''ll go to to make your baby laugh can be surprising. This month, for instance, you might find yourself quacking like a duck and barking like a dog. Why? Six-month-olds love turn-taking games, especially those that involve sounds and language. Let your baby go first, and mimic the sounds he makes. When it''s your turn to lead, you can teach your child — and make him laugh at the same time — with animal noises ("quack-quack," "bow-wow," and so on).
