Easy Hosting Tips for a 3rd Birthday Party for Girls

  • Cap the celebration at about 1.5–2 hours.
  • Don’t schedule it during nap time.
  • Pick just one or two simple activities instead of packing the schedule — a coloring table with crayons and stickers, or a bean bag toss with soft targets, are both easy to set up and perfect for three-year-olds.
  • Serve kid-friendly snacks in bite-sized portions.
  • Snap your photos early, before the sugar kicks in!
  • Set aside a corner with snacks or coffee for the grown-ups (they will thank you).
