For my DIL's shower, I made sugar cookies in shapes of baby bottles and pacifiers. She was having a girl so things were in pink. We made BBQ pork sandwiches with a crock pot recipe and homemade coleslaw. You could make Tortilla roll ups which wouldn't cost that much. Look on the net under some blog spots for some great cooking ideas.
