You can eat the same foods as your friends and family. Just be aware of what and how much you're eating so you get the right balance.
With some planning, you can have sweets like birthday cake, a candy bar or even ice cream! But too many sweets aren't good for anyone, because they have a lot of carbs and can make your blood sugar level rise quickly.
You may need to take more insulin when you eat a sweet treat to balance your blood sugar level.
