From what I've seen, she is not having any bad morning sickness or anything major. Especially since she seems to have plenty of energy to go to the zoo and the lake with her other kid. And if she DOES have a problem doing her job, she needs to talk to HR and figure out how to work PT or go on leave. It's not fair for her to show up to work and slack off and expect the rest of us to pull the slack and have her still collecting full pay. Sorry, but I'm really effing sick of pregnant women taking advantage of their non-pregnant coworkers and it being considered OK. Just because some people don't want kids/aren't having babies anymore/etc, doesn't mean they should have to do the lion's share of the work.
