⚠️ TMI ⚠️ Normal Breastfed 💩?

My son is 5 months old and exclusively breastfed. We will be doing baby led weaning so we haven’t introduced any foods yet. Can anyone tell me if his diapers look like normal breastfed stool? He occasionally has the yellow, seedy, sweet smelling stools (maybe once every couple of weeks?) but the majority are this dark color, very liquidy/goopy, and vinegar smelling. He usually goes 1-2 times per day and if often seeps out the back of his diaper because it’s so watery. I’ve been dairy free for 12 weeks and have seen no improvement.
