It's varied a LOT, depending on the age.
For the first four months or so, she took all her naps on me, usually in a wrap, and I went on tons of long walks and hikes, all of which I wore her for. We put her down some, to let her stretch out and kick her legs and, when she was old enough, grab at toys or play on her playmat, but I wore or carried her for the bulk of the time.
Once she was sitting up by herself at 4.5 months, and rolling, she was a lot more interested in being down on the ground where she could practice all that, but I still wore her for all outings, etc.
As she got mobile, I carried/wore her even less.
For the last couple months, she's been walking, and it's MUCH harder to wear or carry her. She wants to be DOWN, and she lets us know. SHe's happy in the sling or ergo for short periods, but long walks have become much tougher - she doens't like feeling constrained.
My guess is that it varies a lot from baby to baby, though
