I got the Who's Shoes's Id as well as their wrist bracelet Id's. They both are attached with velcro. The Shoe tags go around the girls sandals without bothering them. I got the wrist bracelets as well in case we go to any water parks or what not. (No shoes!) They would work well with the infant. The info is all inside so no one can see the childrens names or your info. I used my lable printer to put the info of our hotels when we travel and our cell number. Have used them at the Zoo, and fairs, etc. Love them. With a 3 and a 4 year old, someone always seems to wander and you don't know they will be when they get "found". After all, we are always telling them not to talk to strangers!
