HELP I HAVE A PICKY EATER IN THE HOUSE!!

Do any of you have a picky eater in your house? I do! Kayden who is three is very picky. He was'nt picky when he first started eating solid foods. I think this started when the doctors told me to give him choices, Big mistake I would never suggest giving your toddlor choices because it messes up the concept of teaching them they need to eat what is in front of them. Now I have been told a good way for them to eat what is in front of them is to let them go hungry for a while and they will eat what is front of them, but I really dont want to do that. He really is'nt much of a meat eater he likes hamburgers that's about it, he likes fresh vegies and cheese. If any of you have any suggestions please give me feedback.
