Express yourself — it's not just the title of a Madonna song, but the catchphrase for tots ready to tell us what's on their minds. Shout Out Clothing ($29) allows lil ones to tell us exactly what they want with t-shirts that feature changeable letters, numbers and symbols. Each shirt comes with a zipper pouch filled with three copies of each letter and number and one of each symbol. Your kid can then spell out their feelings of the day on both the front and back of their shirt, and change their message when they wish. Created by former All My Children actor Colin Egglesfield, these interactive tees also encourage spelling and vocabulary skills in older kids.
