My husband did some serious nesting today, I'm still in shock. Where did his energy come from? I mean he swept, mopped and dusted every room in the house. Did the laundry for all seven of us and finished it off with dinner. I asked him what's going on? He just said "baby's coming soon and you should be resting" kind of nervous now 😩
