I think I actually had the time for 3 smalls... too late now!
Once you got that birth thing out of the way, you find you have too much time on your hands!
It's too bad you're having bad experiences with other swaps. The quality of work varies a lot and it's really hard to tell ahead of time. My first swap, I looked at stuff my partner had done for other swaps and thought "Ewww!" But what she sent me was fabulous. I think all one can do is concentrate on sending your best and not care whether you get anything. Maybe unequal quality is more of a problem in swaps that are for a specific useful thing, like onesies, rather than thematic swaps like ours. But regardless, taking bad photos and not commenting on each others work is unforgivable. Isn't that the real reason we're doing this?
It sounds like you've got the right attitude to it though: annoyed but not bitter!
