When do babies sit

My daughter started sitting up at 5 months by herself and has great posture. She sits and plays on her area rug.

    I think Hayden started sitting around 4.5 months, but wasn't really good at it (as in I felt comfortable leaving her sitting without a pillow behind her) until around 6 months.

      I think in general it's closer to six months alone. I think our oldest was the only one who was close to doing it any earlier than six months, but then again milestones are all blending together in my mind. I'd have to check baby books or my journals to be sure!
