I Spoiled My Grandkids Too Much

So uh, I kinda have this problem. You know how grandparents are supposed to be strict and all that? Yeah well, not me. I'm the grandpa who spoils them rotten. It's like they can sense when I'm around, my phone starts vibrating non-stop with messages from their parents asking what sweets I've given them or if I snuck a toy in when no one was looking. It started last summer when we had this big family trip planned out to the beach, and everyone was getting ready. But little Emma, who's only four, got really nervous about it all, she loves her toys more than anything and wanted to take every single one with her. Her parents were like, no way, and told me to stay out of it, but I just couldn't stand seeing her so upset. So one night, while everyone was asleep, I snuck into Emma's room and packed all her little toys in a bag for the trip, just little things that would fit under my shirt. The next morning she woke up smiling like the biggest sunbeam ever because she had them with her. But then of course, everyone found out and it got to be this whole big deal. It's gotten so bad now where I feel guilty about giving in sometimes but also can't help myself seeing how happy they are. And here comes Thanksgiving next week, and we're all gathering again at my house...I think I need a talk with the family on not feeling like such an awful grandpa who breaks rules left and right.
