Maybe it is, maybe it isn't. You can be a little chubby and still be totally cute though, so even if you have a bigger tummy or whatever, that doesn't mean anything bad.
I can't say, but even if your stomach is fat that doesn't mean you're not beautiful! You can check your bmi (body mass indicator) to see if you are overweight
No. According to your appetite to eat :D
Nah, don't bee so insecure.
