One of the best investments that Mr. S. and I ever made was in our bed. After a lifetime of foam and springs, our hand-made 100% wool bed by Shepherd's Dream really was a dream. It's warm in the winter and cool in the summer. We don't use air conditioning, and the wool bed keeps us so cool and dry during hot muggy summer nights.
To protect it I use big thrifted wool blankets, which I just put down on top of the mattress under the fitted sheet, but considering how many accidents, leaks, and general wetness that accompanies newborns, I wanted something easily changed but still effective. We have two wool puddle pads that we got way back when we got the bed, when Safiya was still a babe, but they're now a little out of our price range (they were well worth the initial cost, though - over the years they've washed beautifully, stayed thick, cozy, and soft, and absorbed wetness and odour very well).
So I thought I'd just make a little stack of puddle pads for on top of the sheets, planning to whisk away the top ones as they get wet. Thrifted wool blankets run about ten dollars around these parts, and after felting them I can get four puddle pads from one (I just cut them and zig-zagged the edges). They're not as thick and luxurious as the ones from Shepherd's Dream, and the weave is a bit looser, but at about $2.50 each, I can afford to double them up....actually, I can afford to sixteen-uple them up, which would be the equivalent cost :-)
Cozy, cozy! One more thing ready for The Bump...
