Which one of this packs is essential to your gameplay?

I picked toddler stuff because I love to play families. The toddler pack adds lots of cute clothes and some hairstyles for them. I don't use the huge play set very often, but for me the pack is still one of my favorites. It's the only pack so far that I've bought on release day. If you like to play families, then I think you'll enjoy this pack. :)
