Bowel movements

Since birth my bowel movements have not been the same. I was struggling with constipation early on and still now (7 months pp) dealing with bowel movements that are hard stool and then end very soft. I drink tons of water 120oz a day, EBF, fiber is around 35-40g a day. I don’t know how or what to do to have a normal BM. I’m also dealing with post BM leakage, it’s gotten better over time but I don’t think the soft stool is helping. Did anyone go through similar and find a solution? is it hormonal? is it diet? thanks in advance!
