Your baby will start talking at around 2 years old, but she can actually communicate with you using her hands much earlier than that - as early as 6 months old! Imagine your baby being able to share with you that he needs a diaper change or would like some milk, or that his tummy aches using sign language instead of fussing, crying, and whining.
Dad seems eager to communicate with me. I just don't think that far right now. So far as mom is able to breastfeed me, the world is fine with me.
