Once you have found a decent baby modeling agency, call and set up an interview. Most agencies are looking for babies with great personalities who love to smile and are easy to work with. While they are assessing your baby, they are also going to look to see what kind of parent you are. These are just a few things to keep in mind. Try and try again if you do not get a job right off the bat. Be patient, consistent, and calm. If you are those things, you will be successful. Stay positive and your baby will be successful.
