Karen Kingsbury series EASY question. What order should I read the series for them to make sense?

So, I have Karen Kingsbury's "Redemption", "Firstborn", "Sunrise" series. They are all about the Baxter family thus called "Baxter Family Drama." I haven't started reading them because I started with the stand-alone books. Now that I have to start reading them, I don't know what order they are supposed to be read in to make most sense.. You know, like in the first series this girl is single and in the other she's married.. If I read the wrong series first, I would be like "uhhh... What?" It doesn't matter if its the right order or not.. I need some advice on the order. Thanks. God bless.
