Was my ex just being nice or do you think there are ulterior motives?

Long story short, my ex and I dated for 4 years. We broke up 3 months ago and live apart now. We have 2 kids together that we coparent. The kids and I recently got sick with a really bad cold and fever so I asked him to drop off some soup and snacks for the kids. After he dropped off the stuff he bought for the kids, I noticed he had also bought me my favorite dessert as well. It was a small gesture but I thought it was thoughtful since I did not ask for anything. I let him know I appreciated it. A few days later, he stopped by again to drop off more food for the kids and included my favorite dessert... again. Does this mean anything?
