Taking away night & nap bottle

So my daughter wants to just drink whole milk and not eat ANYTHING else (literally slaps food out of my hand, forces lips closed, etc) and I think I'm giving her too much (10 oz for nap time and 10 oz night time). WIC tells me it's time to take her bottle away (she's 14 months)

Can I give water at night in a sippy cup? Or is it supposed to be just gone and then I give her a sippy of milk after meals (as WIC tells me to do). I just need this girl to freaking eat some food!
