All in all, first real pizza fail in like, ten years. I've dropped them, torn them, had to repurpose some as calzones.
Bottom on this one got too thin and wet while teaching my daughter how to make her own pie. Went to turn it in my dome and it ripped right through. Fortunately, I was able to burn the oven clean in 5-10 minutes and get another one on.
Calories are absolutely not calories. Being underweight is not a free pass to the buffet. The habits we create for our kids will become lifelong struggles. Normalize healthy eating and help them learn to make good choices.
