I read the same thing about the Infanto slings. Apparently a baby suffocated in one not long ago. I'm no help with the wraps. I have a Moby and am probably the only person on this board who hates it. I also have a Baby Bjorn. Have only used it a couple times (because Jax is too small at the moment for a carrier), but I like it a lot. Of course, I don't do 8 hr hikes or anything like that.
For the monitor I have this one:
Amazon.com: Philips Avent Digital Screen Baby Monitor with DECT Technology: Baby. No video because personally I think it is a waste of money. Works great. The parent unit is super small and you can wear it around your neck while cleaning or whatever. It has connection even when baby is upstairs in our 2 level townhouse and I am down in our dungeon of a basement in the laundry room. Also, it measures the temperature in the room, so it makes it easier to keep the room at the recommended baby temperature at night. We also use the little nightlight that comes with it.
