So according to What to Expect, in addition to the big milestones that Sophia continues to do, there are several mini milestones that should be happening as well.
Of these mini milestones, she's done the Identifying body parts for months, she's long had a sense of humor, and it only continues to get funnier, she's long recognized her own image in a mirror, she's loved to dance for months. She isn't speaking in sentences yet, although while she's got 20+ words, she's very picky about when she wants to use them around other people. I don't know if that means she's a little delayed in her speech, but it wouldn't completely surprise me since she's been ahead in everything else. She loves to sing, loves to play pretend, and has actually recently learned to jump.
