I've heard that it's good to start teaching sign language to babies early on. Aside from hungry and sleepy, what other signs should I try to teach my daughter?

It will definitely be useful! Here’s an article (with additional links to a free baby sign language glossary) on this topic: http://sg.theasianparent.com/mom-teaches-her-3-year-old-and-baby-how-to-speak-through-sign/ Some useful sign languages that you can teach your baby include: “full”, “bath”, “milk”, “stop”, “sleep” You can also add “more”, “eat”, “water” The key is not to overwhelm your baby and start with simple but useful words so that you can communicate with him/her. While on the topic of picking up a language, the best age for language acquisition is before five-/six-year old. This is the period when it is “easiest” for the child to pick up more than one language.
