Turfstone, an open-cell concrete paver, for the path.
Saturday was sunny and Sweet Pea was happy to play in the grass for most of the day. Once we really got into the digging we fenced her in with the final raised bed (photo above), kind of like a giant open-bottom playpen. Sunday was rainy and she fell down, got her hands muddy, and cried as soon as I set her on the ground. She doesn't like to play on wet ground, apparently. So, I spent part of the day working with her in the ERGO on my back, avoiding any tasks that required much bending over. In the afternoon I went inside and hung out with her for a while, then got back to digging once she went down for a nap (thank goodness for baby monitors!)
