I didn't do any nesting/cleaning as such but in the last week before DS was born I made an obscene amount of rock cakes. I've never made them before I was pregnant and I haven't made any since. I didn't even really acknowledge that last week how many I was making and my DP was too polite to tell me (thankfully there were really tasty) but I look back now and crack myself up everytime I think about it. It was so out of character for me.
