What she said, lol!
Seriously, never feed your baby people food, unless it's plain boiled unseasoned chicken or white rice with nothing on it. I know that there are some fruits and veggies that it's okay for them to have, like green beans, apple, carrots, pears, etc. NO citrus, it's too harsh on their tummies. Too much salt and fat can shorten their lives a whole lot, and I know you want to have your darling for as long as possible.
Tell your BF to cut it out, I know that they're expert little beggars, but you must do what's best for them, as they don't know that
I hope that Duke has no more vomiting, poor baby!
