Liquids other than BM?

[CMamma]

I'm posting this separate b/c I think it will/did get lost in my last post about solids...

What about juice or water? Anyone give it to their babies? Or even expressed BM that's been chilled? I know this is silly but it's SOOOOOOOOOOOOOOO hot right now & no kidding he is already pulling my drinks to him if I have one or sucking on the glass & I wonder if it's b/c it's cold. I don't use bottles but he will take a cup so I was wondering if I should give him a little cold water or chilled BM to help cool him down. Any thoughts?

OBTW DS is gonna be 5 mos 6/10.
