I know the feeling!
I've just been wearing my 4 month old, either in front or on my back when I need to do things and she's not happy in her sear/bouncy chair/playpen, etc. I have even been cooking with her on my back, obviously being really careful. Clara seems to like it and she will settle down fairly quickly, and watch what I'm doing or fall asleep.
There are some good videos here http://mamatoto.org/StartHere/OnlineVid ... fault.aspx
on how to tie a baby on your back with a wrap. It requires some practice, but after 4 or 5 times it's fairly straightforward.
Hope it helps, good luck!
