What's picture uno? lol
you post a picture of your baby with something similar to what is in the picture before yours. For instance, you could post a pic of your baby with their tong out, or with an outfit with cars on it, or with your hand holding them... what ever you want to do. Then, the next person posts a picture of their baby with something similar in it as in your pic...
Darn I got nothing...I was just about to put one up that went with the first pic you put.
Ok it's hard to tell but it looks like that is yellow and not orange so I am going with yellow
