My bub is 7 weeks old and i have not yet figured out a good time to do the baths. I usually will do one when baby has woken and i know that she is not real hungry (otherwise she screams right after the bath and cannot settle to eat) OR i bath her when she has had a feed and does not drop straight off to sleep. Its a total guessing game for me at this stage but i am guessing once she is a tad older and in a routine (as such) that i will find the right time. Its difficult isn't it.... !?! Good luck!
