We don't do baths everynight. Usually 3ish times per week. Although, this depends on whether or not he has smeared food in his hair.
We usually play in his room with the lamps on (instead of overhead lights, it's much dimmer with just the lamps). Quiet playing, like looking at puzzles (he mostly just bangs the pieces together), reading books, etc. I will put him in his pajamas, put him in his sleep sack, turn out all the lights (except the nightlight), give him his bottle, rock him for 2-3 minutes, then put him in his crib.
FWIW, I sort of deliberately steered away from some elaborate bedtime routine. I didn't want to be a slave to this long drawn out routine night after night. Mostly, as soon as he's in his sleep sack, he knows it's bedtime. He's never been too much trouble to get to bed so I guess I've never had to figure it out beyond that.
