I married a great guy with 3 daughters. The beginning and up until recently have been great. Their dad isnt used to all the parenting. He was in the military and when he came back he was more worried about trying to save his marriage then parenting the girls simply because he didnt know how, they had/have no direction from BM. I came in we established rules. I enforced them because he wasnt home. I taught them hygiene, how to wash there hair, how often they need to shower and change their underwear. My relationship with them was great! There mother only pays attention to the oldest.
