Nail polish & maternity stuff! I'm addicted to doing my nails and dd's so if I see a good deal on nail polish, I tend to buy a few. As for maternity clothes, I had no idea I would need them so soon this time around. Glad Old Navy was having some awesome sales LOL.
Greek yogurt (my new addiction, seriously eating so much of the stuff I'm expecting to develope an accent)
Can't honestly think of anything I've bought myself that didn't come from a grocery store in I don't know how long... And with that I feel a little sad, I should get myself a non edible treat from time to time...lol
