Caliveg, It's not only important that you continue to offer your child vegetables and other veggie foods for the sake of his future health, but it is also important that your husband get on board with you, because as your son ages, he is far more likely to take his food queues from his dad than from you. Whether your son ends up as a veg or an omni, it's critical that he maintains a healthy, well balanced diet consisting of mostly plant-based foods. This will greatly reduce his risk of developing obesity, heart disease and even cancer. Approach this from a health standpoint with your husband, and he may stop being such a jerk about it.
I have bad genes in my family. We have a strong history of both heart disease and cancer, and my father even developed type 2 diabetes in his early 50s, and he died from brain cancer before his 60th birthday. No male on my father's side of the family has lived to be 70 in at least 6 generations. My husband was totally freaked out at the prospect that he would not be able to "share the experience" of a pro baseball game, camping, and many other events if he couldn't give our son the traditional unhealthy meaty foods like hot dogs and burgers and all that other crap. When I explained that I was not interested in outliving my son and that I wanted to give my child the opportunity to live a full and healthy life, the light clicked on, and he has been 100% on board with raising the baby veg ever since.
I know this is already too long, but based on previous thread, I want to add really fast that I believe that your husband has some serious control issues, and I continue to be concerned for your welfare in the long run. I wish he would agree to counseling, and I hope you will find a way to go without him if he won't go. When your child grows up, he will model the way your husband treats you, and if you don't want your son to trap his spouse and deny her basic choices, then you really need to get some help.
