Hey there.
I am with the Jack Lippman Agency, J.L.A. with Kendall Park. He is a phenomenal children's commercial agent. Super sweet, professional, and his clients work a lot and go out a lot!
I think my boyfriends Agent, J.S. Represents has just started taking on kids as well. He always impresses me. He sends weekly newsletter updates about the business and who booked in the agency, whether its slow or not, etc. He has great communication skills, and is very open that this is a business and if you aren't holding up your end of the deal, i.e. not going to auditions, he doesn't have time for you. A straight shooter.
Hope that helps. E.
P.S. I don't have any kids, i think I got sent to this website initially because my friend owns a clothing line that sells some baby and kids yoga clothes, www.lotusblossomstyle.com
