We had a similar “bike” experience. Santa left bikes for my daughters, then probably 6 and 8. He left them on the back screened in porch. It was dark when the girls got up and they were happily opening presents and enjoying Christmas morning. As dawn came and light began to make the porch visible, I remember the moment when my oldest first saw the bikes. I wish we had a picture of her face. They were full of pure joy and excitement. That sneaky Santa. Christmas 🎅 🎄 🚲 🚲
