Not THAT fragile. Of course you have to be a little careful on lifting etc but your baby is very well protected in there.
Not that fragile you just need to be smart. When my sister was pregnant she still went snowboarding, riding atv, running, working out etc. Just be smart and listen to your body. It's way better to be active during pregnancy then on the couch.
What she said
their tough as old boots. No excuse for not doing the housework for sure.
I really don't know...At work, I've told pregnant girls not to come in when I've suspected something contagious on a resident, and instinctively kept them away from the less trustworthy dementia sufferers. That said, they're probably tougher than we expect.
