Maternity tanks. I have one from Old Navy and one from H & M that I really love. I wear them ALL the time under my non maternity cardigans, which helps stretch my wardrobe a little further.
Tea. I bought a few varieties of pregnancy tea at my local health food store in my first trimester when I was really sick and have replenished the supply several times. It's a nice cozy treat now that it's chilly outside and I'm still restricted from enjoying a good cup o' joe. I occasionally add a few drops of peppermint oil if my stomach is feeling a little unsettled.
Cheese, Cheese, Cheese. Wonderful Cheese.
Back rubs. I made an arrangement with Jim that for every day I'm solely responsible for the caring for the baby, he owes me a 5 minute massage. I don't cash in everyday but some days it can be the absolute BEST 5 minutes.
