Most of my nieces and nephews have weird eating habits, at least compared with myself and my brothers when we were kids.
I have a niece that won't eat any fruit at all ! I asked her why this could be possible, as all fruits look, and taste different, with different textures, but she just looks sulky. I have another nephew who ate baked beans three times a day, until he was about 13-14, but again, no explanation. They both have the same indulgent mother, which might explain a great deal I suppose !
