Have you developed any abnormal habits?

While pregnant with my first, I recently have noticed that I've developed different habits.. I guess they aren't really considered "weird", but out of the ordinary for me.
The biggest one for me is now I CANNOT sit/lay on my furniture or bed with out washing my feet. I wear flip flops all summer, every summer. And I never was bothered by the thought of my feet being dirty after coming inside. I use baby wipes to wash them throughout the day (twice or three times) in addition to bathing regularly. But I don't have peace until I feel they are clean, lol.
I would love to hear if any of you ladies have developed different habits while pregnant, too.
