When you add an item to your Babylist registry, you're essentially adding a link. This link will redirect your guests to the product on the retailer's site. If a retailer puts ALL the colors and sizes for an item at one link, there's no way for the app or Babylist button to know which option you prefer because the link doesn't change when you make the selection. Because of this, we recommend using your note box to specify this information. You can add sizing, color, pattern, length and any additional personalization to the note box. This makes things so much easier for your guests as well!
