It sounds like you are doing very well with this little one.
What State are you in?
From your photo, he looks to be closer to 4 weeks than 3 and it's great that he's mostly able to use the litter tray. I agree with what the others have told you about the diahorrea. First, a visit to the vet with a sample of the kittens stool (they may give you antibiotics if they suspect an infection). If the vet doesn't find any cause, a teaspoon of canned pumpkin, morning and night may just do the trick.
Keep up with bottle feeding until you are sure he's getting enough calories and fluids on his own.
It's fine to give him a bath if he needs it. Gently 'scrub' him with a dryer-warmed towel and then use a hair-dryer set on low.
