My school sounds different--you basically have to compromise (ie fight it out) with about 20 people all doing the same rotation but in different locations. I don't have any kids now but I'm hoping to become pregnant early in 3rd year so I don't want to have to travel hugely pregnant or with a new baby. But, I don't really feel comfortable announcing my baby plans to these people. On top of that, my husband has a fairly serious medical condition that will require major surgery at some point, but I don't know when that will be (but very possibly may be during 3rd year). I don't want to ask for special treatment, but at the same time these seem like legitimate reasons, especially the surgery. I think I may try to use that if push come to shove.
