Your toddler can probably hum and sing songs such as "Twinkle, Twinkle, Little Star" and make three-word sentences like "Cup fall down." She can probably follow a two-part request, like "Come here and turn around so I can comb your hair." Many kids this age also have fun identifying opposites like tall man, short man, or big block, little block. But if your toddler isn't doing all these things, don't worry. Children learn to speak at different rates, and your child may still be working her way up to this stage.
My daughter can sing most of the ABC's and Twinkle Twinkle without missing a beat. She also know the words to Weezer's Buddy Holly and Undone. She follows instructions like go to your room and get the wipes. She does love to point out things like "this is a big one" referring to her blueberries or raisins or such. As far as speaking goes, she rips off sentences like "Mommy, come to my room and play with me. Sit on the floor and play".
She also follows her brother around and does everything he does. Earlier this week the boy ran up to the top of a hill and she followed. He was wearing a backpack. We he reached the top he had to take a couple of backwards steps to steady himself as the backpack caused an unusual center of gravity. When my daughter reached the top she looked over at her brother and took two backwards step to perfectly mimic his assent of the hill.
I prolly should mention that she has a tendency to three bet from the button with suited connectors and will check raise all in with 12 clean outs. My son, on the other hand, plays tighter and is more willing to try and jam the hammer home based on his tight image than to get real creative with medium strength hands.
