Hi all i have an 8 month old that refuses to drink water even on those hot days, does anyone have any advise on how to make her drink water, i worry she might get dehydrated. She is also a fussy eater, i feed her rice alot and have to mix it in with othr vegies or the store baby food but she wont eat it all if its mixed, someone told me that feeding her rice is not good, just wondering if it is ok to give her rice, and what other food she wont spit out at me? cheers
