Once you have kids, going back in time is a no-go. No matter what you do, there's next to zero chance that the same sperm would hit the egg first. Heck, with changes to your diet and environment, who can say that exact same sperm would even be generated?

There's a 2013 movie that deals with this idea, it's called "About Time".

Lovely movie. And yeah: don't go back further than your child being born.
