Drinks ANYTHING only eats pretzels

My 2 year old son will drink anything I put into his bottle or cup but he will not eat... the only thing he has consistently eaten are pretzels... I'm just learning about SI and some of it sounds just like him. I've been saying forever to people how wierd it is that he will only eat certain textures, mostly dry foods, and I thought that his absolutely insane behavior at the barber was normal. He also goes nuts when we try to cut his nails and he loses his mind when I leave a room... he has his own little language but really doesn't talk...Any thoughts?
