A baby or a kid?

Signs Little A is turning into a kid:

-She says "yeah" and "nope."
-She tries to climb trees (as of today).
-Other kids want to play with her.
-Sometimes other moms at the playground refer to her as "the little girl" when talking to their kid.

Signs Little A is still a baby:

-She will still cuddle with her head resting under my chin (when she cuddles at all, that is).
-She may know what to do with most toys, but she will still stick them in her mouth at some point.
-She self-identifies: points to herself and says "baby."
-Sometimes the playground moms call her "the baby."

At 18 months, she is two ounces shy of 20 lbs, and just over two-and-a-half feet tall.
