No nerfs to shamans. Upcoming nerf to feral cat druids (and a bit to resto) but balance looks good.

Patch 3.2 coming up in the next few weeks with some new stuff.
Bear and cat druids getting some lovely new looks.

I believe that some 5 shaman groups have successfully completed some WOTLK heroics, but easier with a tank.
Apart from that nothing much changed. From the sound of it your kid is 3 months so you should be getting more time to multibox again.

Come back the water's fine.
