Maybe she's fat. Maybe she's not sure the baby is viable. Maybe she's deciding whether to stay home. Who knows why she hasn't told you.
You can ask her, which might go fine, or you can wait. Either way, you need to decide if you are going to leave if they have another. Your comfort as a nanny is not something they considered (or should consider) when deciding about a second child, so if you plan to be negative about it when she tells you, maybe you should just move on anyway.
Even though this poster seemed to miss the fact that there already ARE two kids (new baby would be the THIRD, not second), there are a lot of truths here. Having been burned by a pregnant MB deciding to become a stay at home mom at the last possible moment (giving me, her nanny of 3.5 years, 3 weeks notice), I would definitely consider that as a possibility. Especially since she knows how you reacted last time she casually brought up having another baby, she probably realizes you won't be supportive. And being so new at her job she may not get much maternity leave anyway.
But, even if they don't let you go, the question is: would you really want to stay?
Also please don't refer to your nanny charges as "my oldest" and "my youngest."
