Take it from me, baby/child modelling is not fun.
I did a couple of castings with my bonny boy who loved the camera. Thought the money he earned could go into his savings for when he's older.
Both he and I hated it! You have to wait around for hours before anything happens, they only want very submissive kids that will just do as they demand instantly, then you're more or less told to fuck off so they can literally get the next one in and out. It's just like a conveyer belt of kids.
There's no fun involved, my son ended up in tears and I got snotty comments from the staff... "Oh Christ, anybody would think we were bloody murdering him!" while another sniggered and the photographer huffed and growled at him and said "This one isn't working, I haven't got time for this, get the next one in!"
The castings were for the Next catalogue.
I thought the first one was just a bad one-off and tried again. Nope, exactly the same. Horrible experience and I asked the agency to remove him from their books as we wouldn't be going any further with it.
