Does your baby laugh and cry if hear certain words? mine always laughs whenever I say "vanilla" and suddenly cries whenever I say "goodnite" .. so funny!

Yes. When my baby was young, words such as Peekaboo, Ha Ciu, Bu Bu and etc. will make him/her laugh happily. However, I have not encountered my either of my baby will cry when hear certain words. Your baby is so smart to know that he feel sad to go to bed and miss the fun!

Owww....your baby is so clever! My baby laughs when he hear 'Boo!' Coz his sisters love to play peek a boo with him.
