My son talks in his sleep all the time! He'll say random things like "I don't want apples. I want yogurt!". And then he'll wake up the next morning and ask for yogurt. It's pretty funny to hear his random conversations. But it's so loud at night. Sometimes he's screaming "That's mine! Don't take that!" and then he'll start laughing hysterically.

Does your LO talk in his/her sleep? When did it start?
