Add a chalkboard sign that says “FALL into FOUR” and maybe even a leaf pile for jumping or photos.
🎃 Activities: Try pumpkin painting, an apple toss game, or a mini hayride around the yard.
For toddlers, a corn sensory bin is always a hit.
🍎 Food Ideas: Caramel apples, mini pumpkin muffins, “fall snack mix” with candy corn, pretzels, and popcorn.
Serve warm apple cider in cute paper cups.
🎂 Cake Idea: A rustic “naked” cake decorated with mini fondant pumpkins, edible leaves, or cinnamon stick toppers.
📸 Photo Tip: Set up a wooden crate with pumpkins, a birthday sign, and a “four-ever grateful” banner for the sweetest fall birthday photo booth.
