Joy-Anna Duggar knows just how helpful it can be to come from a family with 19 kids. There's always someone to spend time with, get advice from or lend a helping hand. The reality TV star is really enjoying having so many sisters on her side now that she's made her big announcement. The Duggar girls are exceptionally close and are often seen on Counting On taking an active role in each other's lives and helping out where ever they can.
