Girl of few words

My girl was only saying the word "done" for the longest time. Recently.. the last week or so she added "go" and "no" to her words. She also makes cat and pig sounds when asked. She leads me to what she needs and grunts to try to get me to pick her up. I'll say "up?'' and she'll just grunt some more. She can put things where I ask her to and bring things to me. She does simple chores like pouring cat and dog food in the bowls. I worry about how little she talks. My sister has 2 boys and she was telling me hers didn't start until after 2 and I have a cousin who gave birth Jan 2017, hers also says a few words and she says she's not worried. Is anyone else's kiddos not saying many words? We sing, we talk, we dance, we bake, we read, I tell her what I'm doing.. I feel like I'm talking to her from wake to bed!
