I think it sounds just fine, and I can relate to your situation too. I do think it depends on the setup of your house, however. When I put my babe to sleep on the floor (we did this for a while when she was having trouble being put down) I was in the next room, kept her door open, and could hear any whimper. I was always able to attend to her immediately if she woke or stirred. We have lived in several places since DD was born, and I've always put her down in either the same room as me, or the next room. If you have to be further away, I would make sure the room is totally babyproofed, and I'd probably get a baby monitor, just to make sure I knew when baby woke up.
