As a note for future new baby garments--don't remove the tags until you're sure you can use them. Kids regularly grow out of clothes before they even get into them (if you forgot they were in the bottom of a drawer or the back of a closet). A lot of stores are good about letting you exchange clothes with tags for something newer in the right size. So the tags should stay on until you've fitted it on the party of the first part and decided they can wear it for a few weeks. (Yes, weeks. When they're tiny, getting months out of garments is almost impossible.)

Ask me know I know. . . ;-D
