Clothing giftcards: GAP (can use at GAP + Old Navy online maternity), Motherhood Maternity (not a very $$MM place, but whatevs). Its hard to find decent maternity wear.
For fun: TUMS ;D, some compression socks for ankle swelling, Giftcards to ice cream shops, baby design books for decorating a nursery, decaf coffee if she's a caffeine lover...
Congrats Aunt-to-be! When my sister was pregnant, I sent her a care package with Burt's Bees Mama Bee items, a prenatal yoga dvd, some decaf tea, and a bella band.
Haha. My sister did too, come to think of it! Maybe scratch the decaf until you know how addicted she is
She used to work at Starbucks. She is VERY addicted. LOL. I'd be proud if she reduced her order to a single shot of espresso as opposed to the triple-shot norm.
