How exciting!!! That sounds like nesting for sure! I have noticed my desire for all things to be clean/done really starting to kick in the past few days. I still have a lot to do but it's coming along and I feel like doing more than I have felt like doing in a long time!
Hopefully it means good things for you (and me...in a couple of weeks that is!) in the near future...
Just remember to try and balance those spurts of energy with periods of rest. Christin makes a good point of ending up in labor and being WAY tired while everything happens.
