Finishing up my registry, and looking for recs on which monitor to put on there. We live in a large two bedroom apartment, and my mom swears up and down I don't need a monitor, but I'm not convinced. If I'm in the kitchen (and I do spend a lot of time in the kitchen), I wouldn't be able to hear baby from her room unless she was screaming, for example. Thoughts? Recommendations? Models to stay away from?
