Suggestions on how to help my baby sit unassisted
While you can prop your baby in a sitting position almost from day one, true independent sitting doesn't begin until they have head control. Starting at about 4 months, your baby's neck and head muscles strengthen rapidly, and they'll learn to raise and hold their head up while lying on their stomach for tummy time. By 5 months they may be able to sit momentarily without assistance, though you should stay nearby to provide support and surround them with pillows to cushion a possible fall.
After I change my daughter I hold her hands and she does a baby crunch/ sit up, and she sits upright for a few minutes. I also have her sit in her booster chair that has toys on it to play with, so while she is playing she is also contracting and strengthening her ab muscles.
Babies develop skills differently, some more quickly than others, but head control is essential to sitting independently, and sitting is the key to crawling, standing, and learning to walk.
