I think I agree this is more about womens body issues.
From what I have seen, a lot of women see being pregnant as a time they are "allowed" to be pigs/fat and it doesn't matter if they gain weight (ironic since they then bitch about all the weight they have to lose after they have the baby....go figure) since they are gonna look huge no matter what.
This woman who is out and still trying to keep herself healthy with regular exercise (which any doctor in his right mind will tell you is a good thing, sure some exercises might have to be toned down a bit to compensate for pregnancy changes, but by no means do you have to STOP exercising ever if it is a normal pregnancy), is probably making all those other women feel guilty for not doing the same thing they have been making excuses NOT to do ever since they got knocked up, because now they are just "too tired" and "oh, the round ligament pain is too much...". I can tell you the extra tiredness and the ligament pain is a very real thing, but you feel EVEN WORSE if you sit on your ass all day!
I know some women have to go through higher risk pregnancies where it isn't an option as they are ordered bed rest, but this is not the case for every pregnancy. Pretty sure the general rule has always been, do what your body is comfortable with doing. If she was in decent shape before becoming pregnant there is no reason she can't continue working out as normal if it isn't effecting her in a negative way.
Being pregnant doesn't mean you are handicapped ladies!!
Bitches be jelly.
Also, ETA it is nearly always women condemning other women for their choices when pregnancy and children are concerned (as if it were their business to begin with). It's one of the most annoying stupid things, but it seems like when you are pregnant and it becomes visibly obvious, it suddenly becomes EVERYONE elses business what you are doing with your body! Everyone has suggestions and has to give their opinion whether you want it or not! OMG don't eat that, I heard from a friend of a friend of a friend that it isn't good for the baby!!!!
And breastfeeding in public is even worse, I got grossed out looks from women for breastfeeding M (WITH A COVER, even) when he was a newbie and I just grinned at them. Fuck em. If they want to give their kids formula because they didn't want to be bothered with breastfeeding (yes I realize some can't for health/personal reasons also) or hide in a room or a car whenever they have to breastfeed their hungry child so no one sees them ever, they can do that. Me, I would rather go about my life like a normal human being who just happens to also have a baby, thanks.
