Both of my kids love applesauce pouches, Annie's granola bars, peanut butter crackers, bananas, goldfish. I also buy some of the snacks by the brand Plum. I find a lot to choose from at Target.
My daughter chokes on goldfish. (She turned blue once). I would be nervous to send those to daycare. They make half sized baby goldfish now . They're way safer for little tykes. They melt in their mouths pretty quickly. We use them in our church nursery with no issues.
