I'm new to this whole packing a lunch/snacks as we were spoiled with our previous daycare providing everything. Now that DS1 is in kindergarten we have to pack him a lunch and a healthy snack. We are fine with lunch but I have a question about how to pack his snack. We need to keep it separate from his lunch and it has to be something healthy like fruits/veggies/cheese&crackers etc. How do I keep that chilled? I don't want to have 2 lunch boxes but haven't seen anything smaller that I could use a small ice pack with. I'm sure I"m overthinking this and know not everything necessarily needs to be refrigerated. Any suggestions?
