What kind of baby monitors are you ladies using? We have a VTech and the monitor battery life is awful so I'm considering a new one when baby relocates to his own room. I'd love one that you can just use your phone as the monitor but that seems to be more of a security cam thing. I also really want to know the temperature in the room where baby is. The back of our house where the bedrooms are can get really warm sometimes so being able to monitor this is super important to me.
