For those of you who use sign language with your babes, what are the most important signs you find yourself and your little one using? We plan on using it with LO and DH wants to start learning it now so he has a grasp on it. I know quite a bit from using it with my students at work (majority are non-verbal Autistic kiddos), but I don't know what to narrow it down to. So far I was thinking: milk, drink, eat, thank you, please, more. But not sure if there is more I should be considering, and was wondering what other moms were doing before plunking down a ton of cash for books on the topic.
