I think its official Jessaleigh can sit up by herself (at not tip over for awhile). She has been trying to sit up forever it seems, but now I can put her on the floor and walk away for a moment with fearing for her safety. She still tips over eventually, but can catch herself if she goes sideways. Tipping backward is the only real concern and Jessaleigh seems to be OK as long as she in on a soft (rug or pillow) surface.
