[TOMT] A chapter book I read in 3rd grade that follows a family of vampires?

It follows a household of "monsters" it's a mom, dad, kid, and maybe a sibling? Maybe they we werewolves or Frankensteins monsters? I really enjoyed reading it and I think my kids would be interested in it as well. This was about 25 years ago...
