Does anyone else's belly start off flat (or low) in the morning and by mid day it balloons up? This always happens to me and I'm not sure what this is. Sometimes I think I may be allergic to something I eat or.. could it because my stomache muscles are not in the best shape after having 3 kids? Will losing weight eventually stop this? Sorry about all the questions but it really annoys me.

Any advice would be well appreciated and thank you in advance!!
