I've won his heart. . but How Do I win his daughters? Please Guys & girls.?

First of all, breathe. Second, relax. Now, you're lucky that she's five years old. She probably doesn't really understand the relationship you are hoping to have with her father, and so she's not going to resent you like a teenager might. She doesn't think you're going to try to replace mommy, etc. If you really want to win this girl's heart, there's a few things to do. First of all, talk to her like a person, not like an idiot. A lot of people make this mistake, but kids know when they're being talked down to just like anyone else does. Second, be yourself. If you really want to make a good impression on this kid, she has to know that you're comfortable in your own skin. It'll also make it easier to maintain your relationship in the future, because you don't have to pretend to be something you're not. Third, bring a small present, but don't make it look like you're trying to buy love. The girl might not know, but daddy will know for sure. If you don't know what she likes, call him and ask him.
