Our usual sleeping arrangements at home with the babe are baby co-sleeping in mom & dad's bed. Now that she can roll she chooses to sleep on her front (usually not touching/snuggling with anyone). When it was colder, we all wore extra layers to sleep, and kept the blankets down low for safety, so they only covered half our bodies.
I'm having trouble envisioning how to do this in a tent -- it often gets quite cold at night here in upstate NY, even in July/August. Last summer to be comfortable while we slept, we bundled up in many layers and hats, AND had our sleeping bags pulled up to our chins (or even over our heads in some cases).
From reading other threads on this subject, I can see that it makes more sense to make a firm surface out of layers of comforters/blankets (rather than air mattresses), and use blankets on top (rather than each person zipped in a sleeping bag). But it gets way colder in a tent than in our bedroom. I'm worried about the safety of having the blankets pulled up near the baby's head. Also, it seems like the surface we're sleeping on would inevitably get scrunched -- all the issues with blankets and such that we try to avoid to keep co-sleeping safe, especially for a baby who sleeps on her front. Or at 7 months, is she old enough not to worry about this stuff so much anymore?
