To loath something, you have to get them to eat it first!
To be fair, we can get ds to eat small amounts of anything (basically 'cos he is not allowed up fromt he table until he has).
The only thing he consistently won't eat is raw tomato - even cherry tomatoes.
He's not keen on leeks either.
He loves peas, and has eaten nepes (swede in England) successfully when he had his haggis for his Burns Supper (so successful, we repeated it again last week).
He doen't like mushrooms or green/red/yellow/orange peppers - but then, I ouwld never force them on him anyway, as his mother refuses to eat them!
The shame was that I gave him loads of veg as he was being weaned, all of which he ate successfully, but as soon as he was in a position to eat for himslef, all voluntary contact with vegetabels stopped.
We've made a recent breakthorugh with carrots, by telling him that they would help him see in the dark!
