Call your baby Ivy if you want to! It doesn't matter what other people think! And it won't take that long for people to forget what Beyonce's childs name is anyway.
I read that she was actually due in january, because she said in some interview or something that she was six months pregnant in september I think.. So her being due in February seems to have been a rumour, so if that is the case she actually did go to full term.
Having an early c-section doesn't necessarily help against stretchmarks either, I got most of mine in tri 2, and they've stayed the same since, some have even started to fade...
When it comes to the "folding bump" that to me makes it seem more real than fake. A fake bump would be harder and definitely not "fold" just from sitting down, while a real bump moves and changes when we move our bodies, use our muscles and bend over etc. Also, she was leaning forwards to sit down, which means the fabric of the dress was hanging straight down, while her belly was obviously a part of her body which was leaning back. It wasn't her belly that collapsed, just the dress that hung looser as she sat down...
When it comes to having a planned c-section and all the security I don't think that has anything to do with trying to "hide" anything, but rather just wanting to have some privacy. When you are that famous you don't want to end up going into labour in a store, or having paparazzi stalking you taking pictures and videos while you are on your way to the hospital having contractions, or being in a delivery room next to other people who might record your screams on their phones, try to sneak in to get pictures etc.
If anything having a c-section would be worse "cosmetically" than a natural birth, as no one would see any potential scars from a natural birth, so my personal opinion is that the section was done for safety and privacy reasons more than anything else.
I mean, do you have any idea how much money someone would get for a picture of beyonce in labour?? People would climb through 5th floor windows for that kind of money, and that's not something you want to have to worry about while giving birth! It's fine for the "rest" of us, because we get the privacy we want anyway, because no one cares. If this is how she had to do i to get some privacy than that's I think that's absolutely fine!
