Dear [Babysitter's Name],
We just wanted to take a moment to express our heartfelt gratitude for stepping in and taking care of our little ones this past weekend on such short notice. Your kindness and willingness to help mean the world to us. The kids had a blast with you, and knowing they were in such good hands allowed us to enjoy our time away without any worries. Thank you for being such a wonderful part of our family's support system. We truly appreciate you!
Warmest regards,
[Your Name]
