Japan's Otete & Anyo cleans up the print process with custom-made rubber stamps featuring wee one's life-sized hand and foot prints ($116 each). While mom and dad will have to coerce baby to make one print from which the stamps are designed (the site has great tips for obtaining the prints), two to three weeks later, they will receive a stamp with which they can decorate to their heart's content. Each stamp is engraved with the tot's name and birth date and arrives in a beautiful paulownia wooden case.
If you like it then you should put a stamp on it! Capturing a lil one's hand or footprint, either for posterity's sake or for stationery, can be a messy task. Flailing limps and an ink pad don't necessarily mix.
