Aerating wort AFTER pitching ...problems?
I just got side tracked when i was putting my brew into the fermenter and forgot to aerate before hand ... will i damage the yeast aerating with the yeast in the wort? if so why ?

No problem...as long as fermentation isn't over. Mixing in O2 now would be the wise thing to do. You won't break the yeast...they're tough.

Don't worry about it, your yeast will be fine.

I routinely aerate after pitching. No biggie.

I agree with above posts. I have had problems with either aeration or not a big enough pitch. If fermentation has not yet begun, or is within 12 hours of pitching, the yeast have not yet really started attenuating, just have started building more cell walls so your brew can ferment comfortably.
I rock my fermenter back and forth to rile our little friends up, and the 02 left in the head space should be enough to kick off the process.

I'm new to making beer, and got so wrapped up in the new processes that I neglected to properly aerate a batch ... as a result, nothing much was happening. I used my wine whip (drill mounted stir stick) to beat it up a bit, and it's taken off quite nicely now.

In the early '90s, before I knew to aerate, I made several successful beers, without a single failure. Aeration helps, but is NOT the end of the world.
