My favorite book to cuddle up with is ... wow. That's a tough one. Honestly, I like to cuddle up with random fluff that isn't too intense. So whatever is on my kindle at the time. It's a bad answer, but it's an honest one.
My favorite family member to cuddle up with? Wow. That's a dangerous one! HAH! Well, kids don't want to see their parents cuddling up together too much so my husband is out. My son, Jack, is 14 and almost as tall as his very tall dad, so he's out. That leaves my daughter Leila, who is still my peanut, even at 10! We even have a new special cozy blanket that we cuddle up in. YAY!
