I think you are fighting an uphill battle. You are the loser. Hubby will continue to feed her normal kid foods and you will continue to spend your time and money on foods that no one but you are going to eat.
Time to compromise, you need to give in. Hubby will be more willing to compromise if you are. I know you want to feed her a certain way but it's not normal. She will want to eat what she sees you AND hubby eating so you are going to have to compromise and fix foods he will eat. If you don't like those foods then fix the meal for them and fix yourself something else.
**************************************
Again, my point is that as long as you and hubby don't compromise on what is going to be a meal you and he will continue this battle. You will lose. He is going to feed her what he considers normal food and you will be wasting your time and money.
If you cannot compromise with him then he wins. You lose. As long as she sees him eating one thing, and that is food she wants to eat, and you eating food she does not want to eat, he wins, you lose.
You have to come to a consensus. A compromise. He is not going to compromise as long as he is winning...why would he. He will be more likely to compromise if you give some leeway.
