hey ladies! I'm trying to decide on a good baby monitor. I'm torn between just audio vs audio/video. I've heard mixed things about how video is great but it's not 100% necessary. I guess I'm just anxious to spend a ton of money on a video monitor if ultimately I really just pay attention to the audio feature. Can anyone suggest a brand/model that you liked best? Also- what about WiFi monitors? Anyone have insight on those? Thanks!
