If you have a child aged 0-24 months who wakes up smiling from nap, little Gerber, Chubby cheeks, big eyes having exotic looks and appealing that's a baby modelling personality. If your child wears his age in clothing size or smaller, that means he can be casted at his age or younger.Physical development is HUGE at this stage of the game, photographers want to work with kids who can follow directions and are generally easier to deal with. There is a market for small kids with a very easy-going temperament and classic good looks but it's a smaller category so there is less work to go around, but cute baby photographs are in huge demand, Mini Models starting out in the industry typically do editorial spreads for magazines called print modelling if your baby makes it big, then the next step are film, commercials and movies, that's where the real money and work is.
