Sorry but I too thought $60-$70 was a waste of money too. I would rather spend my money on a baby monitor that has a night light.
I bought a night light for Charlie's room from target for $12, then I read that bubs doesn't need a night light, we create their fear of darkness by putting it on for them as a little bubs. So I have it plugged in, if I need to go & check on him quick I just pop the hall light on. If I'm in the room with him for some reason I just turn on the one I have plugged in & off again when he is settled. Anywho that's just my 2cents worth. I think first time around we get caught up in lots of things etc...but end up wasting way too much money on things that are not needed. IMO an expensive nightlight/room therm is one of those things.
