She’s very young…. bunnies usually stay with their siblings till 8 weeks. So remember she is just a baby if she is actually only 6 weeks old.
If she is a bit older than you think, then she may be getting hormonal, but that doesn’t usually occur until around 12 weeks. She also could have a urinary tract infection, as dribbling urine can be a symptom of UTI.
I would not continue any negative reinforcement, she won’t understand what’s going on and it will just harm your relationship. If you want to keep holding her, you can put a towel on your lap, or a waterproof puppy pad. But most bunnies don’t like being held, so as she grows up she may become less tolerant of that anyway.
For hormonal peeing, the best thing to do is get her spayed when she’s old enough. There are some tips on litter training here to help in the mean time: https://binkybunny.com/infocategory/litterbox-training/
