Amber here. I just wanted to post one of my favorite tips. I have an almost teenage son, so I remember when the yogurt company's came up with their convient yogurt tubes. My son was an only child until he was 3, so a big box of yogurt tubes expired before he could finish it. That's when I got my bright idea! FREEZE THEM!!!
Not only did they last longer, but we also found that they make for a yummy frozen dessert! As I had more kids, I found out that I could put the frozen yogurt tube in their lunch bag and by the time they ate, it was thawed out a little, if not all the way, but still very cold, so it's perfect!
I hope this helps and you enjoy!
