At 11 months, E can almost stand up unsupported, but is not there yet.
Me with E at Dave and Busters in April 2006 at a child-friendly work event. Of course, E was still far from the age when she could play any games at Dave and Busters, but I brought her anyway.
11 months: E is trying to stand up on her own, without holding on to anything.
A few days later, E is already doing a pretty good job of standing up on her own.
