I don't about some people but when I was pregnant with my son two years ago, the belly growing thing was gradual. Now that we're trying for #2, I am sure it will just pop one day as they say and this little thing will come in handy earlier! I got the black Bella Band when I was pregnant and ended up using the thing all the time. Really, no joke.
In the beginning of said belly, the band keeps your pants up..always a nice ting since you can't button them anymore, right? Once you get bigger you can use it to cover your belly for a smoother look. And at the end, well they say it will help with some belly support. Silly me didn't do this...next time! The Bella Band is also great for nursing moms, a nice cover up for when you lift your shirt. So I highly recommend getting one and Mom4Life is great place to get that plus so much more!!
